40 /* FUNCTION
41 Split a path into parts at the position of separator.
43 INPUTS
44 name - Split this path
45 separator - Split it at this separator
46 buf - Copy the current part into this buffer
47 oldpos - Begin at this place with the search for separator.
48 If you call this function for the first time, set it
49 to 0.
50 size - The size of the buffer. If the current part of the
51 path is bigger than size-1, only size-1 bytes will
52 be copied.
54 RESULT
55 The next position to continue for the next part or -1 if
56 there is no separator after name+oldpos.
