Hello. The executables compiled with tiny c should run on windows 98?.
I ask this, because, windows 98 use msvcrt.dll v6.0 and is different than
msvcrt.dll v7.0
For example, the sources for the crt for __getmainargs function
in the visual studio 98 (v6.0) prototype is:
_CRTIMP void __cdecl __wgetmainargs
and in visual studio 2010 (v7.0) the prototype is:
_CRTIMP int __cdecl __wgetmainargs
v6.0 says:
Exit: No return value. Values for the arguments to main() are copied
through the passed pointers.
And in the function _setargv (that call):
Exceptions: Terminates with out of memory error if no memory to allocate.
v7.0 says:
Exit: Returns 0 on success, negative if _*setargv returns an error. Values
for the arguments to main() are copied through the passed pointers.
Because this, I think if we want compatibility with this two versions of
msvcrt.dll we cannot use the return value for check success, because v6.0
return void.
I propose this way for check the success of the function:
argv = NULL;
__getmainargs(&argc, &argv, &env, 0, &start_info);
// check success of __getmainargs comparing argv with NULL
if (! argv) {
ExitProcess(-1);
}
Some comments about this?
Tiny c executables should run on windows 98 ?
