 * FILENAME		:	nwplglob.c
 * DESCRIPTION	:	Perl globbing support for NetWare. Other platforms have usually launched
 *                  a separate executable for this in order to take advantage of their
 *                  shell's capability for generating a list of files from a given
 *                  wildcard file spec. On NetWare, we don't have that luxury.
 *                  So we just hack the support into pipe open support (which we also had to hack).
 * Author		:	HYAK
 * Date			:	January 2001.

 Function		:	fnDoPerlGlob

 Description	:	Perl globbing support: Takes an array of wildcard descriptors
                    and produces from it a list of files that the wildcards expand into.
					The list of files is written to the temporary file named by fileName.

 Parameters 	:	argv (IN)	-	Input argument vector.
                    fileName (IN)	-	Input file name for storing globed file names.

 Returns		:	Nothing.
