MEMCHR(3)		   Linux Programmer's Manual		     MEMCHR(3)

NAME
       memchr, memrchr - scan memory for a character

SYNOPSIS
       #include	<string.h>

       void *memchr(const void *s, int c, size_t n);

       void *memrchr(const void	*s, int	c, size_t n);

DESCRIPTION
       The  memchr()  function	scans  the  first  n  bytes of the memory area
       pointed to by s for the character c.  The first byte to match c (inter-
       preted as an unsigned character)	stops the operation.

       The  memrchr()  function	 is like the memchr() function,	except that it
       searches	backwards from the end of the n	bytes pointed to by s  instead
       of forwards from	the front.

RETURN VALUE
       The  memchr()  and memrchr() functions return a pointer to the matching
       byte or NULL if the character does not occur in the given memory	 area.

CONFORMING TO
       The  memchr()  function	conforms  to SVID 3, BSD 4.3, ISO 9899,	POSIX.
       The memrchr() function  is  a  GNU  extension,  available  since	 glibc
       2.1.91.
