wcspbrk

Defined in header <wchar.h> 
wchar_t *wcspbrk( const wchar_t *dest, const wchar_t *str );
-		 (1) (since C95) 
/*QWchar_t*/ *wcspbrk( /*QWchar_t*/ *dest, const wchar_t *str );
-		 (2) (since C23)
-1) Finds the first character in wide string pointed to by dest, that is also in wide string pointed to by str.
-2) Type-generic function equivalent to (1). Let T be an unqualified wide character object type. If a macro definition of each of these generic functions is suppressed to access an actual function (e.g. if (wcspbrk) or a function pointer is used), the actual function declaration (1) becomes visible.

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 <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.
