.SH DESCRIPTION |
|
17 |
.LP
|
|
18 |
The \fIbcmp\fP() function shall compare the first \fIn\fP bytes of |
|
19 |
the area pointed to by \fIs1\fP with the area pointed to |
|
20 |
by \fIs2\fP. |
|
21 |
.SH RETURN VALUE |
|
22 |
.LP
|
|
23 |
The \fIbcmp\fP() function shall return 0 if \fIs1\fP and \fIs2\fP |
|
24 |
are identical; otherwise, it shall return non-zero. Both |
|
25 |
areas are assumed to be \fIn\fP bytes long. If the value of \fIn\fP |
|
26 |
is 0, \fIbcmp\fP() shall return 0. |
|
