memchr - find byte in memory

Syntax	#include <string.h> void *memchr(const void *s, int c, size_t n);
Description	memchr() locates the first occurrence of c in the initial n bytes of the memory area pointed to by s. s is the pointer to the memory area in which byte c is to be found. c is the EBCDIC value of the byte to be found. n is the integer value that specifies the number of bytes to be found in s.
Return val.	Pointer to the position of c in area s
		if successful.
	Null pointer	if c does not occur in the specified area.
Notes	The function is suitable for processing character arrays, which, in contrast to character strings, need not be terminated by the null byte (\0).
