| Defined in header <cstring>

||
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.

[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 <cstring> #include <iomanip> #include <iostream> 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 std::cout << std::quoted(str) << '\n'; if (str) str += std::strspn(str, sep); // skip separator ++cnt; // increment word count } while (str && *str); std::cout << "There are " << cnt << " words\n"; }
Output:
" world, friend of mine!" ", friend of mine!" " of mine!" " mine!" "!" There are 5 words
