bstring(3C) Standard C Library Functions bstring(3C)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 ter‐
minated by a null character). They do not check for the overflow of
any receiving memory area. These functions are similar to the mem‐
cpy(), 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).
