bcopy(3C)

NAME

     bstring, bcopy, bcmp, bzero - bit and byte string 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 on vari-
     able  length  strings  of bytes.  They do not check for null
     bytes as do the functions described on the string(3C) manual
     page.

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

     The bcmp() function compares byte  string  s1  against  byte
     string  s2,  returning 0 if they are identical, 1 otherwise.
     Both strings are assumed to be n  bytes  long.   The  bcmp()
     function always returns 0 when n is 0.

     The bzero() function places n null bytes in the string s.

WARNINGS

     The bcmp() and bcopy() routines  take  parameters  backwards
     from strcmp() and strcpy(), respectively.  See  string(3C).
