| 30 | =head1 DESCRIPTION | ||||
| 31 | |||||
| 32 | C<IO::Handle> is the base class for all other IO handle classes. It is | ||||
| 33 | not intended that objects of C<IO::Handle> would be created directly, | ||||
| 34 | but instead C<IO::Handle> is inherited from by several other classes | ||||
| 35 | in the IO hierarchy. | ||||
| 36 | |||||
| 37 | If you are reading this documentation, looking for a replacement for | ||||
| 38 | the C<FileHandle> package, then I suggest you read the documentation | ||||
| 39 | for C<IO::File> too. | ||||
| 40 | |||||
| 41 | =head1 CONSTRUCTOR | ||||
| 42 | |||||
| 43 | =over 4 | ||||
| 44 | |||||
| 45 | =item new () | ||||
| 46 | |||||
| 47 | Creates a new C<IO::Handle> object. | ||||
| 48 | |||||
| 49 | =item new_from_fd ( FD, MODE ) | ||||
| 50 | |||||
| 51 | Creates an C<IO::Handle> like C<new> does. | ||||
| 52 | It requires two parameters, which are passed to the method C<fdopen>; | ||||
| 53 | if the fdopen fails, the object is destroyed. Otherwise, it is returned | ||||
| 54 | to the caller. | ||||
| 55 | |||||
| 56 | =back | ||||
| 57 | |||||
| 58 | =head1 METHODS | ||||
| 59 | |||||
| 60 | See L<perlfunc> for complete descriptions of each of the following | ||||
| 61 | supported C<IO::Handle> methods, which are just front ends for the | ||||
| 62 | corresponding built-in functions: | ||||
| 63 | |||||
| 64 | $io->close | ||||
| 65 | $io->eof | ||||
| 66 | $io->fcntl( FUNCTION, SCALAR ) | ||||
| 67 | $io->fileno | ||||
| 68 | $io->format_write( [FORMAT_NAME] ) | ||||
| 69 | $io->getc | ||||
| 70 | $io->ioctl( FUNCTION, SCALAR ) | ||||
| 71 | $io->read ( BUF, LEN, [OFFSET] ) | ||||
| 72 | $io->print ( ARGS ) | ||||
| 73 | $io->printf ( FMT, [ARGS] ) | ||||
| 74 | $io->say ( ARGS ) | ||||
| 75 | $io->stat | ||||
| 76 | $io->sysread ( BUF, LEN, [OFFSET] ) | ||||
| 77 | $io->syswrite ( BUF, [LEN, [OFFSET]] ) | ||||
| 78 | $io->truncate ( LEN ) | ||||
| 79 | |||||
| 80 | See L<perlvar> for complete descriptions of each of the following | ||||
| 81 | supported C<IO::Handle> methods. All of them return the previous | ||||
| 82 | value of the attribute and takes an optional single argument that when | ||||
| 83 | given will set the value. If no argument is given the previous value | ||||
| 84 | is unchanged (except for $io->autoflush will actually turn ON | ||||
| 85 | autoflush by default). | ||||
| 86 | |||||
| 87 | $io->autoflush ( [BOOL] ) $| | ||||
| 88 | $io->format_page_number( [NUM] ) $% | ||||
| 89 | $io->format_lines_per_page( [NUM] ) $= | ||||
| 90 | $io->format_lines_left( [NUM] ) $- | ||||
| 91 | $io->format_name( [STR] ) $~ | ||||
| 92 | $io->format_top_name( [STR] ) $^ | ||||
| 93 | $io->input_line_number( [NUM]) $. | ||||
| 94 | |||||
| 95 | The following methods are not supported on a per-filehandle basis. | ||||
| 96 | |||||
| 97 | IO::Handle->format_line_break_characters( [STR] ) $: | ||||
| 98 | IO::Handle->format_formfeed( [STR]) $^L | ||||
| 99 | IO::Handle->output_field_separator( [STR] ) $, | ||||
| 100 | IO::Handle->output_record_separator( [STR] ) $\ | ||||
| 101 | |||||
| 102 | IO::Handle->input_record_separator( [STR] ) $/ | ||||
| 103 | |||||
| 104 | Furthermore, for doing normal I/O you might need these: | ||||
| 105 | |||||
| 106 | =over 4 | ||||
| 107 | |||||
| 108 | =item $io->fdopen ( FD, MODE ) | ||||
| 109 | |||||
| 110 | C<fdopen> is like an ordinary C<open> except that its first parameter | ||||
| 111 | is not a filename but rather a file handle name, an IO::Handle object, | ||||
| 112 | or a file descriptor number. (For the documentation of the C<open> | ||||
| 113 | method, see L<IO::File>.) | ||||
| 114 | |||||
| 115 | =item $io->opened | ||||
| 116 | |||||
| 117 | Returns true if the object is currently a valid file descriptor, false | ||||
| 118 | otherwise. | ||||
| 119 | |||||
| 120 | =item $io->getline | ||||
| 121 | |||||
| 122 | This works like <$io> described in L<perlop/"I/O Operators"> | ||||
| 123 | except that it's more readable and can be safely called in a | ||||
| 124 | list context but still returns just one line. If used as the conditional | ||||
| 125 | within a C<while> or C-style C<for> loop, however, you will need to | ||||
| 126 | emulate the functionality of <$io> with C<< defined($_ = $io->getline) >>. | ||||
| 127 | |||||
| 128 | =item $io->getlines | ||||
| 129 | |||||
| 130 | This works like <$io> when called in a list context to read all | ||||
| 131 | the remaining lines in a file, except that it's more readable. | ||||
| 132 | It will also croak() if accidentally called in a scalar context. | ||||
| 133 | |||||
| 134 | =item $io->ungetc ( ORD ) | ||||
| 135 | |||||
| 136 | Pushes a character with the given ordinal value back onto the given | ||||
| 137 | handle's input stream. Only one character of pushback per handle is | ||||
| 138 | guaranteed. | ||||
| 139 | |||||
| 140 | =item $io->write ( BUF, LEN [, OFFSET ] ) | ||||
| 141 | |||||
| 142 | This C<write> is somewhat like C<write> found in C, in that it is the | ||||
| 143 | opposite of read. The wrapper for the perl C<write> function is | ||||
| 144 | called C<format_write>. However, whilst the C C<write> function returns | ||||
| 145 | the number of bytes written, this C<write> function simply returns true | ||||
| 146 | if successful (like C<print>). A more C-like C<write> is C<syswrite> | ||||
| 147 | (see above). | ||||
| 148 | |||||
| 149 | =item $io->error | ||||
| 150 | |||||
| 151 | Returns a true value if the given handle has experienced any errors | ||||
| 152 | since it was opened or since the last call to C<clearerr>, or if the | ||||
| 153 | handle is invalid. It only returns false for a valid handle with no | ||||
| 154 | outstanding errors. | ||||
| 155 | |||||
| 156 | =item $io->clearerr | ||||
| 157 | |||||
| 158 | Clear the given handle's error indicator. Returns -1 if the handle is | ||||
| 159 | invalid, 0 otherwise. | ||||
| 160 | |||||
| 161 | =item $io->sync | ||||
| 162 | |||||
| 163 | C<sync> synchronizes a file's in-memory state with that on the | ||||
| 164 | physical medium. C<sync> does not operate at the perlio api level, but | ||||
| 165 | operates on the file descriptor (similar to sysread, sysseek and | ||||
| 166 | systell). This means that any data held at the perlio api level will not | ||||
| 167 | be synchronized. To synchronize data that is buffered at the perlio api | ||||
| 168 | level you must use the flush method. C<sync> is not implemented on all | ||||
| 169 | platforms. Returns "0 but true" on success, C<undef> on error, C<undef> | ||||
| 170 | for an invalid handle. See L<fsync(3c)>. | ||||
| 171 | |||||
| 172 | =item $io->flush | ||||
| 173 | |||||
| 174 | C<flush> causes perl to flush any buffered data at the perlio api level. | ||||
| 175 | Any unread data in the buffer will be discarded, and any unwritten data | ||||
| 176 | will be written to the underlying file descriptor. Returns "0 but true" | ||||
| 177 | on success, C<undef> on error. | ||||
| 178 | |||||
| 179 | =item $io->printflush ( ARGS ) | ||||
| 180 | |||||
| 181 | Turns on autoflush, print ARGS and then restores the autoflush status of the | ||||
| 182 | C<IO::Handle> object. Returns the return value from print. | ||||
| 183 | |||||
| 184 | =item $io->blocking ( [ BOOL ] ) | ||||
| 185 | |||||
| 186 | If called with an argument C<blocking> will turn on non-blocking IO if | ||||
| 187 | C<BOOL> is false, and turn it off if C<BOOL> is true. | ||||
| 188 | |||||
| 189 | C<blocking> will return the value of the previous setting, or the | ||||
| 190 | current setting if C<BOOL> is not given. | ||||
| 191 | |||||
| 192 | If an error occurs C<blocking> will return undef and C<$!> will be set. | ||||
| 193 | |||||
| 194 | =item binmode( [LAYER] ) | ||||
| 195 | |||||
| 196 | C<binmode> sets C<binmode> on the underlying C<IO> object, as documented | ||||
| 197 | in C<perldoc -f binmode>. | ||||
| 198 | |||||
| 199 | C<binmode> accepts one optional parameter, which is the layer to be | ||||
| 200 | passed on to the C<binmode> call. | ||||
| 201 | |||||
| 202 | =back | ||||
| 203 | |||||
| 204 | |||||
| 205 | If the C functions setbuf() and/or setvbuf() are available, then | ||||
| 206 | C<IO::Handle::setbuf> and C<IO::Handle::setvbuf> set the buffering | ||||
| 207 | policy for an IO::Handle. The calling sequences for the Perl functions | ||||
| 208 | are the same as their C counterparts--including the constants C<_IOFBF>, | ||||
| 209 | C<_IOLBF>, and C<_IONBF> for setvbuf()--except that the buffer parameter | ||||
| 210 | specifies a scalar variable to use as a buffer. You should only | ||||
| 211 | change the buffer before any I/O, or immediately after calling flush. | ||||
| 212 | |||||
| 213 | WARNING: The IO::Handle::setvbuf() is not available by default on | ||||
| 214 | Perls 5.8.0 and later because setvbuf() is rather specific to using | ||||
| 215 | the stdio library, while Perl prefers the new perlio subsystem instead. | ||||
| 216 | |||||
| 217 | WARNING: A variable used as a buffer by C<setbuf> or C<setvbuf> B<must not | ||||
| 218 | be modified> in any way until the IO::Handle is closed or C<setbuf> or | ||||
| 219 | C<setvbuf> is called again, or memory corruption may result! Remember that | ||||
| 220 | the order of global destruction is undefined, so even if your buffer | ||||
| 221 | variable remains in scope until program termination, it may be undefined | ||||
| 222 | before the file IO::Handle is closed. Note that you need to import the | ||||
| 223 | constants C<_IOFBF>, C<_IOLBF>, and C<_IONBF> explicitly. Like C, setbuf | ||||
| 224 | returns nothing. setvbuf returns "0 but true", on success, C<undef> on | ||||
| 225 | failure. | ||||
| 226 | |||||
| 227 | Lastly, there is a special method for working under B<-T> and setuid/gid | ||||
| 228 | scripts: | ||||
| 229 | |||||
| 230 | =over 4 | ||||
| 231 | |||||
| 232 | =item $io->untaint | ||||
| 233 | |||||
| 234 | Marks the object as taint-clean, and as such data read from it will also | ||||
| 235 | be considered taint-clean. Note that this is a very trusting action to | ||||
| 236 | take, and appropriate consideration for the data source and potential | ||||
| 237 | vulnerability should be kept in mind. Returns 0 on success, -1 if setting | ||||
| 238 | the taint-clean flag failed. (eg invalid handle) | ||||
| 239 | |||||
| 240 | =back | ||||
| 241 | |||||
| 242 | =head1 NOTE | ||||
| 243 | |||||
| 244 | An C<IO::Handle> object is a reference to a symbol/GLOB reference (see | ||||
| 245 | the L<Symbol> package). Some modules that | ||||
| 246 | inherit from C<IO::Handle> may want to keep object related variables | ||||
| 247 | in the hash table part of the GLOB. In an attempt to prevent modules | ||||
| 248 | trampling on each other I propose the that any such module should prefix | ||||
| 249 | its variables with its own name separated by _'s. For example the IO::Socket | ||||
| 250 | module keeps a C<timeout> variable in 'io_socket_timeout'. | ||||

| 258 | =head1 BUGS | ||||
| 259 | |||||
| 260 | Due to backwards compatibility, all filehandles resemble objects | ||||
| 261 | of class C<IO::Handle>, or actually classes derived from that class. | ||||
| 262 | They actually aren't. Which means you can't derive your own | ||||
| 263 | class from C<IO::Handle> and inherit those methods. | ||||
