wcsrchr()

QNX SDP8.0C Library ReferenceAPIDeveloper

Find the last occurrence of a wide character in a string

Synopsis:

#include <wchar.h>

wchar_t * wcsrchr( const wchar_t * ws,
                   wchar_t wc );

Arguments:

ws: The wide-character string that you want to search.
wc: The wide character that you're looking for.

Library:

libc

Use the -l c option to qcc to link against this library. This library is usually included automatically.

Description:

The wcsrchr() function finds the last occurrence of wc in the string pointed to by ws. The terminating NUL character is considered to be part of the string.

Returns:

A pointer to the located wide character, or NULL if wc doesn't occur in the string.

Classification:

ANSI, POSIX 1003.1


Safety:
Cancellation point	No
Signal handler	Yes
Thread	Yes
