wchar_t* wcsstr( const wchar_t* dest, const wchar_t* src ); | (since C95) |
Finds the first occurrence of the wide string src
in the wide string pointed to by dest
. The terminating null characters are not compared.
dest | - | pointer to the null-terminated wide string to examine |
src | - | pointer to the null-terminated wide string to search for |
Pointer to the first character of the found substring in dest
, or a null pointer if no such substring is found. If src
points to an empty string, dest
is returned.
#include <stdio.h> #include <locale.h> #include <wchar.h> int main(void) { setlocale(LC_ALL, "ru_RU.UTF-8"); wchar_t str[5][64] = { L"Строка, где есть подстрока 'но'.", L"Строка, где такой подстроки нет.", L"Он здесь.", L"Здесь он.", L"Его нет." }; for (size_t i = 0; i < 5; ++i) { if (wcsstr(str[i], L"но")) { wprintf(L"%ls\n", str[i]); } } }
Output:
Строка, где есть подстрока 'но'.
