| 1 | package Fcntl; | ||||
| 2 | |||||
| 3 | =head1 NAME | ||||
| 4 | |||||
| 5 | Fcntl - load the C Fcntl.h defines | ||||
| 6 | |||||
| 7 | =head1 SYNOPSIS | ||||
| 8 | |||||
| 9 | use Fcntl; | ||||
| 10 | use Fcntl qw(:DEFAULT :flock); | ||||
| 11 | |||||
| 12 | =head1 DESCRIPTION | ||||
| 13 | |||||
| 14 | This module is just a translation of the C F<fcntl.h> file. | ||||
| 15 | Unlike the old mechanism of requiring a translated F<fcntl.ph> | ||||
| 16 | file, this uses the B<h2xs> program (see the Perl source distribution) | ||||
| 17 | and your native C compiler. This means that it has a | ||||
| 18 | far more likely chance of getting the numbers right. | ||||
| 19 | |||||
| 20 | =head1 NOTE | ||||
| 21 | |||||
| 22 | Only C<#define> symbols get translated; you must still correctly | ||||
| 23 | pack up your own arguments to pass as args for locking functions, etc. | ||||
| 24 | |||||
| 25 | =head1 EXPORTED SYMBOLS | ||||
| 26 | |||||
| 27 | By default your system's F_* and O_* constants (eg, F_DUPFD and | ||||
| 28 | O_CREAT) and the FD_CLOEXEC constant are exported into your namespace. | ||||
| 29 | |||||
| 30 | You can request that the flock() constants (LOCK_SH, LOCK_EX, LOCK_NB | ||||
| 31 | and LOCK_UN) be provided by using the tag C<:flock>. See L<Exporter>. | ||||
| 32 | |||||
| 33 | You can request that the old constants (FAPPEND, FASYNC, FCREAT, | ||||
| 34 | FDEFER, FEXCL, FNDELAY, FNONBLOCK, FSYNC, FTRUNC) be provided for | ||||
| 35 | compatibility reasons by using the tag C<:Fcompat>. For new | ||||
| 36 | applications the newer versions of these constants are suggested | ||||
| 37 | (O_APPEND, O_ASYNC, O_CREAT, O_DEFER, O_EXCL, O_NDELAY, O_NONBLOCK, | ||||
| 38 | O_SYNC, O_TRUNC). | ||||
| 39 | |||||
| 40 | For ease of use also the SEEK_* constants (for seek() and sysseek(), | ||||
| 41 | e.g. SEEK_END) and the S_I* constants (for chmod() and stat()) are | ||||
| 42 | available for import. They can be imported either separately or using | ||||
| 43 | the tags C<:seek> and C<:mode>. | ||||
| 44 | |||||
| 45 | Please refer to your native fcntl(2), open(2), fseek(3), lseek(2) | ||||
| 46 | (equal to Perl's seek() and sysseek(), respectively), and chmod(2) | ||||
| 47 | documentation to see what constants are implemented in your system. | ||||
| 48 | |||||
| 49 | See L<perlopentut> to learn about the uses of the O_* constants | ||||
| 50 | with sysopen(). | ||||
| 51 | |||||
| 52 | See L<perlfunc/seek> and L<perlfunc/sysseek> about the SEEK_* constants. | ||||
| 53 | |||||
| 54 | See L<perlfunc/stat> about the S_I* constants. | ||||
