NAME Check::Socket - Check socket communication functionality. SYNOPSIS use Check::Socket qw(check_socket $ERROR_MESSAGE); my $ret = check_socket(); print $ERROR_MESSAGE."\n"; DESCRIPTION There is need of check for socket communication functionality in tests. Actually we have many duplicated and not same check code in distributions. Sic! Intent of this module is create common code for check and test all behaviours. Extra thing is error message which describe issue. SUBROUTINES "check_socket" my $ret = check_socket(); Check possibility of socket communication functionality on system. Return value is 1 as possible use of socket functionality or 0 as not possible use of socket functionality. If return value is 0, set $ERROR_MESSAGE variable. Returns 0/1. ERRORS check_socket(): Set $ERROR_MESSAGE variable if $ret is 0: Socket extension unavailable. IO extension unavailable. $^O: AF_UNIX unavailable or disabled. $^O: Compiled without TCP/IP stack v4. $^O: Skip sockets on CI. $^O: UNIX domain sockets not implemented. EXAMPLE1 use strict; use warnings; use Check::Socket qw(check_socket $ERROR_MESSAGE); if (check_socket()) { print "We could use socket communication.\n"; } else { print "We couldn't use socket communication.\n"; print "Error message: $ERROR_MESSAGE\n"; } # Output on Unix: # We could use socket communication. EXAMPLE2 use strict; use warnings; use Check::Fork qw(check_fork); use Check::Socket qw(check_socket); if (! check_fork()) { print "We couldn't fork.\n"; print "Error message: $Check::Fork::ERROR_MESSAGE\n"; } elsif (! check_socket()) { print "We couldn't use socket communication.\n"; print "Error message: $Check::Socket::ERROR_MESSAGE\n"; } else { print "We could use fork and socket communication.\n"; } # Output on Unix: # We could use fork and socket communication. DEPENDENCIES Config, Exporter, Readonly, Socket. SEE ALSO Check::Fork Check fork functionality.
