Defined in header <cstring>
const char* strpbrk( const char* dest, const char* breakset );
char* strpbrk(       char* dest, const char* breakset );

Scans the null-terminated byte string pointed to by dest for any character from the null-terminated byte string pointed to by breakset, and returns a pointer to that character.

Parameters

dest	-	pointer to the null-terminated byte string to be analyzed
breakset	-	pointer to the null-terminated byte string that contains the characters to search for

Return value

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

Notes

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

Example

Run this code

#include <iostream>
#include <cstring>
 
int main()
{
    const char* str = "hello world, friend of mine!";
    const char* sep = " ,!";
 
    unsigned int cnt = 0;
    do {
       str = std::strpbrk(str, sep); // find separator
       if(str) str += std::strspn(str, sep); // skip separator
       ++cnt; // increment word count
    } while(str && *str);
 
    std::cout << "There are " << cnt << " words\n";
}

Output:

There are 5 words
