*dll_argv.c - __setargv() routine for use with C Run-Time as a DLL (CRTDLL)

|

|
|
*Purpose:
|
||
|
|
* This object is part of the start-up code for EXE's linked with
|
||
|
|
* CRTDLL.LIB/MSVCRT.LIB. This object will be linked into the user
|
||
|
|
* EXE if and only if the user explicitly links with SETARGV.OBJ.
|
||
|
|
* The code in this object sets the flag that is passed to the
|
||
|
|
* C Run-Time DLL to enable wildcard expansion of the argv[] vector.
|
||
|
|
*
|
||
|
|
*Revision History:
|
||
|
|
* 03-04-94 SKS Initial version
|
||
|
|
* 03-27-01 PML Now return an int (vs7#231220)

/***

*__setargv - dummy version (for wildcard expansion) for CRTDLL.DLL model only
|
||
|
|
*
|
||
|
|
*Purpose:
|
||
|
|
* If the EXE that is linked with CRTDLL.LIB is linked explicitly with
|
||
|
|
* SETARGV.OBJ, the call to _setargv() in the C Run-Time start-up code
|
||
|
|
* (above) will call this routine, instead of calling a dummy version of
|
||
|
|
* _setargv() which will do nothing. This will set to one the static
|
||
|
|
* variable which is passed to __getmainargs(), thus enabling wildcard
|
||
|
|
* expansion of the command line arguments.
|
||
|
|
*
|
||
|
|
* In the statically-linked C Run-Time models, _setargv() and __setargv()
|
||
|
|
* are the actual routines that do the work, but this code exists in
|
||
|
|
* CRTDLL.DLL and so some tricks have to be played to make the same
|
||
|
|
* SETARGV.OBJ work for EXE's linked with both LIBC.LIB and CRTDLL.LIB.
|
||
|
|
*
|
||
|
|
*Entry:
|
||
|
|
* The static variable _dowildcard is zero (presumably).
|
||
|
|
*
|
||
|
|
*Exit:
|
||
|
|
* The static variable _dowildcard is set to one, meaning that the
|
||
|
|
* routine __getmainargs() in CRTDLL.DLL *will* do wildcard expansion on
|
||
|
|
* the command line arguments. (The default behavior is that it won't.)
|
||
|
|
* Always return 0 (full version in DLL code returns -1 on error)
|
||
|
|
*
|
||
|
|
*Exceptions:
