memchr, memrchr — scan memory for a character
#include <string.h>
void
*memchr( |
const void * | s, |
| int | c, | |
| size_t | n); |
void
*memrchr( |
const void * | s, |
| int | c, | |
| size_t | n); |
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.
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.
The memchr() function
conforms to SVr4, 4.3BSD, C89, C99, POSIX.1-2001. The
memrchr() function is a GNU
extension, available since glibc 2.1.91.
