Subject:	Re: globbing and shells
Status:	O

Assuming you wanted to distribute a program, the only drawback of adding the globbing
routines to your program is the extra size overhead. In other words, if the shell expands  
wildcards then calls to glob produce nothing--all files are single strings in argv[?]...
Of course you could also test for various shells and decide on a technique at run-time,
but this introduces more overhead and complicates matters greatly.

Why not  create a library of routines that address the short comings of working in the dos  
environment, add a standard include file to prototype/define the routines and link to it
at compile time? 


#include <stdio.h>
#include <stdlib.h>
#include <mylib.h>

void
main(argc, argv)
	int argc;
	char **argv;
{
	FILE *infile, *outfile;
	char **globv;
	char progname[8] = basename(argv[0]);

	................... getopts stuff ....................
	if (globv = glob_filenname(argv[1].................
	[ rest of your program here ]
}

>gcc -O myprog.c -o myprog -lmy
