.SH DESCRIPTION
|
|
The byte string functions perform operations on strings (byte arrays)
|
|
that are not necessarily null-terminated.
|
|
See the individual man pages
|
|
for descriptions of each function.
|
|
.SH NOTES
|
|
The functions
|
|
.BR bcmp (),
|
|
.BR bcopy (),
|
|
and
|
|
.BR bzero ()
|
|
are obsolete.
|
|
Use
|
|
.BR memcmp (),
|
|
.BR memcpy (),
|
|
and
|
|
.BR memset ()
|
|
instead.
|
|
.\" The old functions are not even available on some non-GNU/Linux systems.
