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. | ||||
