Subject: Re: globbing and shells
 
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 ]
}
