std::wcspbrk

From cppreference.com
< cpp‎ | string‎ | wide
Defined in header <cwchar>
const wchar_t* wcspbrk( const wchar_t* dest, const wchar_t* str );
      wchar_t* wcspbrk(       wchar_t* dest, const wchar_t* str );

Finds the first character in wide string pointed to by dest, that is also in wide string pointed to by str.

Parameters

dest - pointer to the null-terminated wide string to be analyzed
src - pointer to the null-terminated wide string that contains the characters to search for

Return value

Pointer to the first character in dest, that is also in str, or a null pointer if no such character exists.

Notes

The name stands for "wide character string pointer break", because it returns a pointer to the first of the separator ("break") characters.

Example

#include <iostream>
#include <cwchar>
#include <iomanip>
 
int main()
{
    const wchar_t* str = L"Hello world, friend of mine!";
    const wchar_t* sep = L" ,!";
 
    unsigned int cnt = 0;
    do {
       str = std::wcspbrk(str, sep); // find separator
       std::wcout << std::quoted(str) << L'\n';
       if (str) str += std::wcsspn(str, sep); // skip separator
       ++cnt; // increment word count
    } while (str && *str);
 
    std::wcout << L"There are " << cnt << L" words\n";
}

Output:

" world, friend of mine!"
", friend of mine!"
" of mine!"
" mine!"
"!"
There are 5 words
