wcspbrk

From cppreference.com
< c‎ | string‎ | wide
Defined in header <wchar.h>
wchar_t* wcspbrk( const wchar_t* dest, const wchar_t* str );
(since C95)

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

Contents

[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 str, or NULL 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

#include <stdio.h>
#include <wchar.h>
 
int main(void)
{
    const wchar_t* str = L"Hello world, friend of mine!";
    const wchar_t* sep = L" ,!";
 
    unsigned int cnt = 0;
    do {
       str = wcspbrk(str, sep); // find separator
       if (str) str += wcsspn(str, sep); // skip separator
       ++cnt; // increment word count
    } while (str && *str);
 
    wprintf(L"There are %u words.\n", cnt);
}

Output:

There are 5 words.
