-/**
- * Copy a memory segment to another, possibly overlapping, segment,
- * stop when a NUL byte or a specified byte is encountered.
- * 
- * This is a slibc extension added for completeness.
- * It is only available if GNU extensions are available.
- * 
- * @param   whither  The destination memory segment.
- * @param   whence   The source memory segment.
- * @param   c        The stop byte.
- * @param   maxlen   The maximum number of bytes to copy.
- *                   NOTE that if the resulting string at least this
- *                   long, no NUL byte will be written to `whither'.
- *                   On the otherhand, if the resultnig string is
- *                   shorter, `whither` will be filled with NUL bytes
- *                   until this amount of bytes have been written.
- * @return           `NULL` if `c` was not encountered, otherwise
- *                   the position of `c` translated to `whither`,
- *                   that is, the address of `whither` plus the
- *                   number of copied characters; the address of
- *                   one character passed the last written non-NUL
- *                   character.
