||
| 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.
Parameters
| dest | - | pointer to the null-terminated wide string to examine |
| src | - | pointer to the null-terminated wide string to search for |
Return value
Pointer to the first character of the found substring in dest, or NULL if no such substring is found. If src points to an empty string, dest is returned.
Example
Run this code
#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'.
