std::wcspbrk

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

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

[edit] 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

[edit] Return value

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

[edit] Notes

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

[edit] Example

Run this code
#include <cwchar>
#include <iomanip>
#include <iostream>
 
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
