NAME

bcopy — copy byte string

LIBRARY

Standard C Library (libc, -lc)

SYNOPSIS

#include <strings.h>

void
bcopy(const void *src, void *dst, size_t len);

DESCRIPTION

The bcopy() function copies len bytes from string src to string dst. The two strings may overlap. If len is zero, no bytes are copied.

This function is obsolete. The functions memcpy(3) and/or memmove(3) should be used instead. Note that bcopy() takes its src and dst arguments in the opposite order from these.

SEE ALSO

memccpy(3), memcpy(3), memmove(3), strcpy(3), strncpy(3)

STANDARDS

The bcopy() function conforms to IEEE Std 1003.1-2001 (“POSIX.1”). The IEEE Std 1003.1-2004 (“POSIX.1”) revision marked it as legacy; the IEEE Std 1003.1-2008 (“POSIX.1”) revision removed it from the specification.

HISTORY

A bcopy() function appeared in 4.2BSD.
