DESCRIPTION
These functions operate on variable length strings of bytes. They do not check for terminating NUL bytes as the routines listed in string(3) do.
See the specific manual pages for more information.
SEE ALSO
bcmp(3), bcopy(3), bzero(3), memccpy(3), memchr(3), memcmp(3), memcpy(3), memmove(3), memset(3)
STANDARDS
The functions memchr(),
memcmp(), memcpy(),
memmove(), and memset()
conform to ANSI X3.159-1989
(“ANSI C89”).
HISTORY
The bcmp(),
bcopy(), and bzero()
functions first appeared in 4.2BSD. The
memchr(), memcmp(),
memccpy(), memcpy(), and
memset() functions first appeared in
AT&T System V UNIX and were reimplemented
for 4.3BSD-Tahoe. The
memmove() function first appeared in
4.3BSD-Reno.
