35 use. If it is the null byte, white space is used as the separator,
36 and leading white space is discarded. Otherwise, each occurrence
37 of the separator character delimits a field (and thus some fields
38 may be empty). The array and size arguments may be used to reuse
39 the same memory. This function is not tied to uuconf; the only way
40 it can fail is if malloc or realloc fails. */
