memchr — locate
byte in byte string
Standard C Library (libc, -lc)
#include
<string.h>
void *
memchr(const
void *b, int c,
size_t len);
void *
memrchr(const
void *b, int c,
size_t len);
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.
The memchr() and
memrchr() functions return a pointer to the byte
located, or NULL if no such byte exists within len
bytes.

ISO/IEC 9899:1990
(“ISO C90”).
The memrchr() function is a GNU extension
