29   pointing to *LINESIZE bytes of space.  Store the input bytes
30   starting at *LINEPTR + OFFSET, and null-terminate them.  Reallocate
31   the buffer as necessary, but if NMAX is not GETNLINE_NO_LIMIT
32   then do not allocate more than NMAX bytes; if the line is longer
33   than that, read and discard the extra bytes.  Stop reading after
34   after the first occurrence of DELIM1 or DELIM2, whichever comes
35   first; a delimiter equal to EOF stands for no delimiter.  Read the
36   input bytes from STREAM.
37   Return the number of bytes read and stored at *LINEPTR + OFFSET (not
38   including the NUL terminator), or -1 on error or EOF.  */
