Описание (Description)
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.1‐2017 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.
Возвращаемое значение (Return value)
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.
