bstring(3) Library Functions Manual bstring(3)Name
bcopy, bcmp, bzero, ffs - bit and byte string operations
Syntax
void bcopy(b1, b2, length)
char *b1, *b2;
int length;
bcmp(b1, b2, length)
char *b1, *b2;
int length;
void bzero(b1, length)
char *b1;
int length;
ffs(i)
int i;
Description
The functions and operate on variable length strings of bytes. They do not check for null bytes as the routines in do.
The function copies length bytes from string b1 to the string b2.
The function compares byte string b1 against byte string b2, returning zero if they are identical, non-zero otherwise. Both strings are
assumed to be length bytes long.
The function places length 0 bytes in the string b1.
The ffs finds the first bit set in the argument passed it and returns the index of that bit. Bits are numbered starting at 1. A return
value of 0 indicates the value passed is zero.
Restrictions
The and routines take parameters backwards from and

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
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).
