.SH DESCRIPTION |
|
15 |
.LP
|
|
16 |
The \fIstrrchr\fP() function shall locate the last occurrence of \fIc\fP |
|
17 |
(converted to a \fBchar\fP) in the string pointed to |
|
18 |
by \fIs\fP. The terminating null byte is considered to be part of |
|
19 |
the string. |
|
20 |
.SH RETURN VALUE |
|
21 |
.LP
|
|
22 |
Upon successful completion, \fIstrrchr\fP() shall return a pointer |
|
23 |
to the byte or a null pointer if \fIc\fP does not occur in |
|
24 |
the string. |

|
|
33 |
The following example uses \fIstrrchr\fP() to get a pointer to the |
|
34 |
base name of a file. The \fIstrrchr\fP() function searches |
|
35 |
backwards through the name of the file to find the last \fB'/'\fP |
|
36 |
character in \fIname\fP. This pointer (plus one) will point |
|
37 |
to the base name of the file. |
