wcspbrk - cppreference.com

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 dest is of type const T*, the return type is const wchar_t*.
Otherwise, if dest is of type T*, the return type is wchar_t*.
Otherwise, the behavior is undefined.

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.

[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 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

#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:
