POSIX::1003::Confstr - POSIX access to confstr()
use POSIX::1003::Confstr; # import all use POSIX::1003::Confstr 'confstr'; my $path = confstr('_CS_PATH'); use POSIX::1003::Confstr '_CS_PATH'; my $path = _CS_PATH; use POSIX::1003::Confstr '%confstr'; my $key = $confstr{_CS_PATH}; $confstr{_CS_NEW_CONF} = $key;
With confstr() you can retreive string values from the operating system. It is the counterpart of sysconf() which can only return numeric values.
confstr()
sysconf()
Returns the confstr value related to the NAMEd constant. The NAME must be a string. undef will be returned when the NAME is not known by the system.
undef
example:
my $path = confstr('_CS_PATH') || '/bin:/usr/bin';
Returns a list with all known names, unsorted.
This exported variable is a (tied) HASH which maps _CS_* names to the unique numbers to be used with the system's confstr() function.
_CS_*
The following constants where detected on your system when the module got installed. The second column shows the value which where returned at that time.
