This means that it has a +far more likely chance of getting the numbers right. + +=head1 NOTE + +Only C<#define> symbols get translated; you must still correctly +pack up your own arguments to pass as args for locking functions, etc. + +=head1 EXPORTED SYMBOLS + +By default your system's F_* and O_* constants (eg, F_DUPFD and +O_CREAT) and the FD_CLOEXEC constant are exported into your namespace. + +You can request that the flock() constants (LOCK_SH, LOCK_EX, LOCK_NB +and LOCK_UN) be provided by using the tag C<:flock>. See L<Exporter>. + +You can request that the old constants (FAPPEND, FASYNC, FCREAT, +FDEFER, FEXCL, FNDELAY, FNONBLOCK, FSYNC, FTRUNC) be provided for +compatibility reasons by using the tag C<:Fcompat>. For new +applications the newer versions of these constants are suggested +(O_APPEND, O_ASYNC, O_CREAT, O_DEFER, O_EXCL, O_NDELAY, O_NONBLOCK, +O_SYNC, O_TRUNC). + +For ease of use also the SEEK_* constants (for seek() and sysseek(), +e.g. SEEK_END) and the S_I* constants (for chmod() and stat()) are +available for import. They can be imported either separately or using +the tags C<:seek> and C<:mode>. + +Please refer to your native fcntl(2), open(2), fseek(3), lseek(2) +(equal to Perl's seek() and sysseek(), respectively), and chmod(2) +documentation to see what constants are implemented in your system. + +See L<perlopentut> to learn about the uses of the O_* constants +with sysopen(). + +See L<perlfunc/seek> and L<perlfunc/sysseek> about the SEEK_* constants. + +See L<perlfunc/stat> about the S_I* constants. + +=cut + +use strict; +our($VERSION, @ISA, @EXPORT, @EXPORT_OK, %EXPORT_TAGS, $AUTOLOAD); + +require Exporter; +use XSLoader (); +@ISA = qw(Exporter); +BEGIN { + $VERSION = "1.06"; +} + +# Items to export into callers namespace by default +# (move infrequently used names to @EXPORT_OK below) +@EXPORT = + qw( + FD_CLOEXEC + F_ALLOCSP + F_ALLOCSP64 + F_COMPAT + F_DUP2FD + F_DUPFD + F_EXLCK + F_FREESP + F_FREESP64 + F_FSYNC + F_FSYNC64 + F_GETFD + F_GETFL + F_GETLK + F_GETLK64 + F_GETOWN + F_NODNY + F_POSIX + F_RDACC + F_RDDNY + F_RDLCK + F_RWACC + F_RWDNY + F_SETFD + F_SETFL + F_SETLK + F_SETLK64 + F_SETLKW + F_SETLKW64 + F_SETOWN + F_SHARE + F_SHLCK + F_UNLCK + F_UNSHARE + F_WRACC + F_WRDNY + F_WRLCK + O_ACCMODE + O_ALIAS + O_APPEND + O_ASYNC + O_BINARY + O_CREAT + O_DEFER + O_DIRECT + O_DIRECTORY + O_DSYNC + O_EXCL + O_EXLOCK + O_LARGEFILE + O_NDELAY + O_NOCTTY + O_NOFOLLOW + O_NOINHERIT + O_NONBLOCK + O_RANDOM + O_RAW + O_RDONLY + O_RDWR + O_RSRC + O_RSYNC + O_SEQUENTIAL + O_SHLOCK + O_SYNC + O_TEMPORARY + O_TEXT + O_TRUNC + O_WRONLY + ); + +# Other items we are prepared to export if requested +@EXPORT_OK = qw( + DN_ACCESS + DN_ATTRIB + DN_CREATE + DN_DELETE + DN_MODIFY + DN_MULTISHOT + DN_RENAME + FAPPEND + FASYNC + FCREAT + FDEFER + FDSYNC + FEXCL + FLARGEFILE + FNDELAY + FNONBLOCK + FRSYNC + FSYNC + FTRUNC + F_GETLEASE + F_GETSIG + F_NOTIFY + F_SETLEASE + F_SETSIG + LOCK_EX + LOCK_MAND + LOCK_NB + LOCK_READ + LOCK_RW + LOCK_SH + LOCK_UN + LOCK_WRITE + O_IGNORE_CTTY + O_NOATIME + O_NOLINK + O_NOTRANS + SEEK_CUR + SEEK_END + SEEK_SET + S_IFSOCK S_IFBLK S_IFCHR S_IFIFO S_IFWHT S_ENFMT + S_IREAD S_IWRITE S_IEXEC + S_IRGRP S_IWGRP S_IXGRP S_IRWXG + S_IROTH S_IWOTH S_IXOTH S_IRWXO + S_IRUSR S_IWUSR S_IXUSR S_IRWXU + S_ISUID S_ISGID S_ISVTX S_ISTXT + _S_IFMT S_IFREG S_IFDIR S_IFLNK + &S_ISREG &S_ISDIR &S_ISLNK &S_ISSOCK &S_ISBLK &S_ISCHR &S_ISFIFO + &S_ISWHT &S_ISENFMT &S_IFMT &S_IMODE +); +# Named groups of exports +%EXPORT_TAGS = ( + 'flock' => [qw(LOCK_SH LOCK_EX LOCK_NB LOCK_UN)], + 'Fcompat' => [qw(FAPPEND FASYNC FCREAT FDEFER FDSYNC FEXCL FLARGEFILE + FNDELAY FNONBLOCK FRSYNC FSYNC FTRUNC)], + 'seek' => [qw(SEEK_SET SEEK_CUR SEEK_END)], + 'mode' => [qw(S_ISUID S_ISGID S_ISVTX S_ISTXT + _S_IFMT S_IFREG S_IFDIR S_IFLNK + S_IFSOCK S_IFBLK S_IFCHR S_IFIFO S_IFWHT S_ENFMT + S_IRUSR S_IWUSR S_IXUSR S_IRWXU + S_IRGRP S_IWGRP S_IXGRP S_IRWXG + S_IROTH S_IWOTH S_IXOTH S_IRWXO + S_IREAD S_IWRITE S_IEXEC + S_ISREG S_ISDIR S_ISLNK S_ISSOCK + S_ISBLK S_ISCHR S_ISFIFO + S_ISWHT S_ISENFMT + S_IFMT S_IMODE + )], +); + +# Force the constants to become inlined +BEGIN { + XSLoader::load 'Fcntl', $VERSION; +} + +sub S_IFMT { @_ ?
