BSTRING 3C "Apr 15, 2002"
NAME
bstring, bcopy, bcmp, bzero - memory operations
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 bcopy(), bcmp(), and bzero() functions operate as efficiently as possible on memory areas (arrays of bytes bounded by a count, not terminated by a null character). They do not check for the overflow of any receiving memory area. These functions are similar to the memcpy(), memcmp(), and memset() functions described on the memory(3C) manual page.

The bcopy() function copies n bytes from memory area s1 to s2. Copying between objects that overlap will take place correctly.

The bcmp() function compares the first n bytes of its arguments, returning 0 if they are identical and 1 otherwise. The bcmp() function always returns 0 when n is 0.

The bzero() function sets the first n bytes in memory area s to 0.

WARNINGS

The bcopy() function takes parameters backwards from memcmp(). See memory(3C).
