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
       (interpreted 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.
