int CompareType (  const char *  str, const char *  typestr )

Returns 0 on syntax match, -1 on failure. Definition at line 234 of file toyparse.c. Referenced by FindInList().

char** Explode (  const char *  strIn  )

Returns a NULL-terminated array of string tokens on success, NULL on failure. Definition at line 305 of file toyparse.c. References AllocateArray(). Referenced by LineToTypes().
