, and returns a pointer to that character.

[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
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
