-.SH DESCRIPTION
-The
-.BR memchr ()
-function scans the initial
-.I n
-bytes of the memory
-area pointed to by
-.I s
-for the first instance of
-.IR c .
-Both
-.I c
-and the bytes of the memory area pointed to by
-.I s
-are interpreted as
-.IR "unsigned char" .
-.P
-The
-.BR memrchr ()
-function is like the
-.BR memchr ()
-function,
-except that it searches backward from the end of the
-.I n
-bytes pointed to by
-.I s
-instead of forward from the beginning.
-.P
-The
-.BR rawmemchr ()
-function is similar to
-.BR memchr (),
-but it assumes
-(i.e., the programmer knows for certain)
-that an instance of
-.I c
-lies somewhere in the memory area starting at the location pointed to by
-.IR s .
-If an instance of
-.I c
-is not found, the behavior is undefined.
-Use either
-.BR strlen (3)
-or
-.BR memchr (3)
-instead.
-.SH RETURN VALUE
-The
-.BR memchr ()
-and
-.BR memrchr ()
-functions return a pointer
-to the matching byte or NULL if the character does not occur in
-the given memory area.
-.P
-The
-.BR rawmemchr ()
-function returns a pointer to the matching byte.
