The caller of WinMain() incorrectly parses the command line if e.g. the space is present in the path or filename of the executable. The lpCmdLine then contains part of the filename at the beginning.
/* program.c*/
#include <windows.h>
int APIENTRY WinMain( HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nCmdShow )
{
MessageBox(NULL, lpCmdLine, "lpCmdLine:", MB_OK );
return 0;
}
$ gcc program.c -mwin32 $ mv a.exe "a a.exe" $ "./a a.exe" "1st parameter" 2nd\ parameter
Then MessageBox shows that lpCmdLine contains: a.exe" "1st parameter" "2nd parameter"
If program is compiled with -mno-cygwin the bug is not present and lpCmdLine is ok:
"1st parameter" "2nd parameter"
