locale::msgcat
Msgcat(3pm) User Contributed Perl Documentation Msgcat(3pm)
NAME
Locale::Msgcat - Perl extension for blah blah blah
SYNOPSIS
use Locale::Msgcat;
$cat = new Locale::Msgcat;
$rc = $cat->catopen(name, oflag);
$msg = $cat->catgets(set_number, message_number, string);
$rc = $cat->catclose();
DESCRIPTION
The Locale::Msgcat module allows access to the message catalog functions which are available on some systems. A new Locale::Msgcat object
must first be created for each catalog which has to be open at a given time.
The catopen operation opens the catalog whose name is given as argument. The oflag can be either 0 or NL_CAT_LOCALE (usually 1) which is
the recommended value.
The catgets message retrieves message_number for the set_number message set, and if not found returns string.
The catclose function should be used when access to a catalog is not needed anymore.
EXAMPLES
use Locale::Msgcat;
$cat = new Locale::Msgcat;
unless ($cat->catopen("whois.cat", 1)) {
print STDERR "Can't open whois catalog.
";
exit(1);
}
printf "First message, first set : %s
", $cat->catgets(1, 1, "not found");
unless ($cat->catclose()) {
print STDERR "Can't close whois catalog.
";
exit(1);
}
The above example would print the first message from the first message set found in the whois catalog, or if not found it would print "not
found".
