Expanding wildcard arguments
Wildcard argument expansion is Microsoft-specific.
When you run a C program, you can use either of the two wildcards, the question mark (
?) and the asterisk (
*), to specify filename and path arguments on the command line.
By default, wildcards aren't expanded in command-line arguments. You can replace the normal argument vector
argv loading routine with a version that does expand wildcards by linking with the
wsetargv.obj file. If your program uses a
main function, link with
setargv.obj. If your program uses a
wmain function, link with
wsetargv.obj. Both of these have equivalent behavior.
To link with
wsetargv.obj, use the
/link option. For example:
cl example.c /link setargv.obj
The wildcards are expanded in the same manner as operating system commands.
