[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 src, 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
Run this code
#include <cwchar>#include <iomanip>#include <iostream> int main(){constwchar_t* str = L"Hello world, friend of mine!";constwchar_t* sep = L" ,!"; unsignedint cnt =0;do{ str = std::wcspbrk(str, sep);// find separatorstd::wcout<<std::quoted(str)<< L'\n';if(str) str +=std::wcsspn(str, sep);// skip separator++cnt;// increment word count}while(str &&*str); std::wcout<< L"There are "<< cnt << L" words\n";}
Output:
" world, friend of mine!" ", friend of mine!" " of mine!" " mine!" "!" There are 5 words
