/*
**  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.
