memchr - Search for a character in memory area

Definition	#include <string.h> void *memchr(const void *s, int c, size_t n); memchr searches for the first occurrence of the character c in the first n bytes of the memory area to which s points.
Return val.	Pointer to the position of c in area s
		if successful.
	NULL pointer	if c is not contained in the specified area.
Notes	The function is suitable for processing character arrays containing the null byte (\0), since memchr does not interpret the null byte as the ’end of text’. The following two prototypes of the memchr function are applicable to C++: const void *memchr(const void *s, int c, size_t n); void *memchr( void *s, int c, size_t n);
