NAME
wcschr —
wide-character string scanning operation
SYNOPSIS
#include
<wchar.h>
wchar_t *wcschr(const wchar_t *ws, wchar_t wc);
DESCRIPTION
[CX] The functionality described on this reference page is aligned with the ISO C standard. Any conflict between the requirements described here and the ISO C standard is unintentional. This volume of IEEE Std 1003.1-2001 (“POSIX.1”) defers to the ISO C standard.
The wcschr () function shall
locate the first occurrence of wc in the wide-character
string pointed to by
ws. The application
shall ensure that the value of wc is a character
representable as a type
wchar_t
and a wide-character code corresponding to a valid character in the current
locale. The terminating null wide-character code is considered to be part of
the wide-character string.
RETURN VALUE
Upon completion, wcschr () shall return a
pointer to the wide-character code, or a null pointer if the wide-character
code is not found.
ERRORS
No errors are defined.
EXAMPLES
None.
APPLICATION USAGE
None.
RATIONALE
None.
FUTURE DIRECTIONS
None.
