/*
** stptok() -- public domain by Ray Gardner, modified by Bob Stout
**
** You pass this function a string to parse, a buffer to receive the
** "token" that gets scanned, the length of the buffer, and a string of
** "break" characters that stop the scan. It will copy the string into
** the buffer up to any of the break characters, or until the buffer is
** full, and will always leave the buffer null-terminated. It will
** return a pointer to the first non-breaking character after the one
** that stopped the scan.
