wmemchr \- find a wide character in memory

.SH SYNOPSIS
|
|

|

\fB#include <wchar.h>

|

|
|
wchar_t *wmemchr(const wchar_t *\fP\fIws\fP\fB, wchar_t\fP \fIwc\fP\fB,

.SH DESCRIPTION
|
|
.LP
|
|
The \fIwmemchr\fP() function shall locate the first occurrence of
|
|
\fIwc\fP in the initial \fIn\fP wide characters of the
|
|
object pointed to by \fIws\fP. This function shall not be affected
|
|
by locale and all \fBwchar_t\fP values shall be treated
|
|
identically. The null wide character and \fBwchar_t\fP values not
|
|
corresponding to valid characters shall not be treated
|
|
specially.
|
|
.LP
|
|
If \fIn\fP is zero, the application shall ensure that \fIws\fP is
|
|
a valid pointer and the function behaves as if no valid
|
|
occurrence of \fIwc\fP is found.
|
|
.SH RETURN VALUE
|
|
.LP
|
|
The \fIwmemchr\fP() function shall return a pointer to the located
|
|
wide character, or a null pointer if the wide character does
|
|
not occur in the object.
|
|
.SH ERRORS
