Synopsis

#include <strings.h>

void bcopy(const void *s1, void *s2, size_t n);

int bcmp(const void *s1, const void *s2, size_t n);

void bzero(void *s, size_t n);

Description

The functions bcopy(), bcmp(), and bzero() operate on variable length strings of bytes. They do not check for null bytes as the routines in string(3C) do.

bcopy() copies n bytes from string s1 to the string s2. Overlapping strings are handled correctly.

bcmp() compares byte string s1 against byte string s2, returning zero if they are identical, 1 otherwise. Both strings are assumed to be n bytes long. bcmp() using n zero bytes always returns zero.

bzero() places n 0 bytes in the string s.
