/*** *dll_argv.c - __setargv() routine for use with C Run-Time as a DLL (CRTDLL) * * Copyright (c) 1994-1997, Microsoft Corporation. All rights reserved. * *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. * *******************************************************************************/ #ifdef CRTDLL #include #include /*** *__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.) * *Exceptions: * *******************************************************************************/ extern int _dowildcard; /* should be in */ #ifdef WPRFLAG void __cdecl __wsetargv ( void ) #else /* WPRFLAG */ void __cdecl __setargv ( void ) #endif /* WPRFLAG */ { _dowildcard = 1; } #endif /* CRTDLL */
