memchr—find character in memory #include <string.h>
void *memchr(const void *src, int c, size_t length);
Description
This function searches memory starting at *src for the
character c. The search only ends with the first
occurrence of c, or after length characters; in
particular, NUL does not terminate the search.
Returns
If the character c is found within length characters
of *src, a pointer to the character is returned. If
c is not found, then NULL is returned.
Portability
memchr is ANSI C.
memchr requires no supporting OS subroutines.
