std::wcsstr
From cppreference.com
| Defined in header <cwchar>
|
||
const wchar_t* wcsstr( const wchar_t* dest, const wchar_t* src );
|
||
wchar_t* wcsstr( wchar_t* dest, const wchar_t* src );
|
||
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 a null pointer if no such substring is found. If src points to an empty string, dest is returned.
Example
Run this code
#include <clocale>
#include <cwchar>
#include <iostream>
int main()
{
wchar_t const* origin = L", , , , , .";
wchar_t const* target = L"";
wchar_t const* result = origin;
std::setlocale(LC_ALL, "en_US.utf8");
std::wcout << L"Substring to find: \"" << target << L"\"\n"
<< L"String to search: \"" << origin << L"\"\n\n";
for (; (result = std::wcsstr(result, target)) != nullptr; ++result)
std::wcout << L"Found: \"" << result << L"\"\n";
}
Possible output:
Substring to find: ""
String to search: ", , , , , ."
Found: ", , , , ."
Found: ", ."
