memchr, memrchr - scan memory for a character
Návod, kniha: Linux Programmer's Manual
#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 SVID 3, BSD 4.3, ISO 9899, POSIX. The
memrchr() function is a GNU extension, available since glibc 2.1.91.
