strpbrk

From cppreference.com
< c‎ | string‎ | byte
Defined in header <string.h>
char* strpbrk( const 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.

Contents

[edit] 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

[edit] Return value

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

[edit] Notes

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

[edit] Example

#include <stdio.h>
#include <string.h>
 
int main(void)
{
    const char* str = "hello world, friend of mine!";
    const char* sep = " ,!";
 
    unsigned int cnt = 0;
    do {
       str = strpbrk(str, sep); // find separator
       if(str) str += strspn(str, sep); // skip separator
       ++cnt; // increment word count
    } while(str && *str);
 
    printf("There are %d words\n", cnt);
}

Output:

There are 5 words
