WCSSTR(3P)                POSIX Programmer's Manual               WCSSTR(3P)

PROLOG         top

       This manual page is part of the POSIX Programmer's Manual.  The Linux
       implementation of this interface may differ (consult the
       corresponding Linux manual page for details of Linux behavior), or
       the interface may not be implemented on Linux.

NAME         top

       wcsstr — find a wide-character substring

SYNOPSIS         top

       #include <wchar.h>
       wchar_t *wcsstr(const wchar_t *restrict ws1,
           const wchar_t *restrict ws2);

DESCRIPTION         top

       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
       POSIX.1‐2008 defers to the ISO C standard.
       The wcsstr() function shall locate the first occurrence in the wide-
       character string pointed to by ws1 of the sequence of wide characters
       (excluding the terminating null wide character) in the wide-character
       string pointed to by ws2.

RETURN VALUE         top

       Upon successful completion, wcsstr() shall return a pointer to the
       located wide-character string, or a null pointer if the wide-
       character string is not found.
       If ws2 points to a wide-character string with zero length, the
       function shall return ws1.
