AFAIK, there is no function to return the directory of an application.  I
made such a function for DDE (doom editor), so it has the QuitDDE_Error
function call in it--change it to whatever you want...  There's also no
guarantee it works, even though it runs perfectly in DDE. =)  BTW, just pass
any full filename + path to this function, and it modifies the
full_file_path....can be changed, of course.  If you want to pass the
filename of the .exe running (user could have changed it from default,
etc.), then "#include <crt0.h>" and do something like "path =
strdup(__crt0_argv[0]);", then pass path to get_path().  =)


Well, here it is:


char *get_path(char *full_file_path)
{
  char *path, *path_sep[50], **sep=&full_file_path;
  unsigned int path_sep_num = 0, path_add, char_add, string_char_add = 0;
  short int runable;

  path = (char*)malloc(512);
  if (path==NULL)
     QuitDDE_Error(LOWMEM, "Can't allocate enough memory for get_path!");

  while ((path_sep[path_sep_num] = strsep(sep, "/"))) {
        path_sep_num++;
  }

  for (path_add = 0; path_add < (path_sep_num-1); path_add++)
  {
    for (char_add = 0; char_add < strlen(path_sep[path_add]); char_add++)
    {
         path[string_char_add] = path_sep[path_add][char_add];
         string_char_add++;
    }
    path[string_char_add] = '/';
    string_char_add++;
  }
  path[string_char_add] = '\0';

  full_file_path = strdup(path);
  free(path);

  return full_file_path;
}
