Return to lglob.h CVS log

Up to [local] / src / usr.bin / less

less uses the "lessecho" command to do globbing on systems that
don't have libc glob routines.  We have glob(3) but for some reason,
less only uses this on DOS w/ djgppc.  I have pared down lglob.h
to just have the glob(3) bits and to include glob.h itself.  This
removes the need for lessecho on OpenBSD.

/*
 * Macros to define the method of doing filename "globbing".
 * There are three possible mechanisms:
 *   1.	GLOB_LIST
 *	This defines a function that returns a list of matching filenames.
 *   2. GLOB_NAME
 *	This defines a function that steps thru the list of matching
 *	filenames, returning one name each time it is called.
 *   3. GLOB_STRING
 *	This defines a function that returns the complete list of
 *	matching filenames as a single space-separated string.
