NAME

     memchr -- locate byte in byte string

LIBRARY

     Standard C Library (libc, -lc)

SYNOPSIS

     #include <string.h>

     void *
     memchr(const void *b, int c, size_t len);

     void *
     memrchr(const void *b, int c, size_t len);

DESCRIPTION

     The memchr() function locates the first occurrence of c (converted to an unsigned char) in string b.

     The memrchr() function behaves like memchr(), except that it locates the last occurrence of c in string b.

RETURN VALUES

     The memchr() and memrchr() functions return a pointer to the byte located, or NULL if no such byte exists within len bytes.

SEE ALSO

STANDARDS

     The memchr() function conforms to ISO/IEC 9899:1990 (``ISO C90'').

     The memrchr() function is a GNU extension and conforms to no standard.

HISTORY

     The memrchr() function first appeared in GNU libc 2.1.91, this implementation first appeared in FreeBSD 6.4, coming from OpenBSD 4.3.
