CONSTANTS

%pathconf

This exported variable is a tied HASH which maps _PC_* names on unique numbers, to be used with the system's pathconf() and fpathconf() functions.

The following constants where detected on your system when the module got installed. The second column shows the value which where returned for a random file at the time.

During installation, a symbol table will get inserted here.
