Ok. I forgot that we was in lite-C that code was from C. Sorry for that.
Here is the lite-C version.

Code:

---

#include <windows.h>
#include <stdio.h>
	
void SetPathToExe(void)
{    
      char  exePath[260+1] ; // MAX_PATH = 260
      GetModuleFileName( GetModuleHandle(0), exePath, sizeof( exePath )-1 ) ;   
      _chdir( exePath ) ;
}
