Problem:

I am attempting to insert the _setargv module into my standard C
library to expand wild-card command line arguments as documented on
Page 130 of the "Microsoft C 5.10 Optimizing Compiler User's Guide."

When I invoke the LIB utility to remove the old _setargv module
from the C library, I get the warning message "setargv.obj: warning
U4151: '__setargv': symbol defined in module stdargv, redefinition
ignored."

My program is supposed to expand *.dat and print the names of all .dat
files in the current directory. When I link my compiled code to the
modified C library, I do not receive any errors. However, when I run
my program, it prints out *.dat instead of expanding the wild card.

Response:

This is an error in documentation. The name of the module that you
should extract from the C run-time library is stdargv. To replace this
module with the module for expanding wild cards, use the LIB utility
and enter the following module names after the Operations: prompt:

Operations: -stdargv+setargv

After performing this operation with LIB, linking the modified C
library to your code will now permit the expansion of wild-card
arguments by means of the argv[] array that is one of the main()
function arguments.

Note that you may link the object file setargv.obj with your code and
an unmodified C run-time library to allow the expansion of wild cards.
The replacement of module stdargv with setargv.obj allows wild-card
expansion without explicitly linking in "setargv.obj" each time.

C Version 4.00 and its documentation about the wild-card expansion
library module had a similar problem.

If you are using C Version 4.00, search for wild card and setargv for
more information.
