.SH DESCRIPTION
.sp
.LP
The \fBbcmp()\fR function compares two byte arrays of length \fIlen\fR.
.SH RETURN VALUES
.sp
.LP
The \fBbcmp()\fR function returns \fB0\fR if the arrays are identical, or \fB1\fR if they are not.
.SH CONTEXT
.sp
.LP
The \fBbcmp()\fR function can be called from user, interrupt, or kernel context.
