| 5 | SYNOPSIS |
|---|
| 6 | #include <wchar.h> |
|---|
| 7 | wchar_t *wcspbrk(const wchar_t *<[s]>, const wchar_t *<[set]>); |

| 9 | DESCRIPTION |
|---|
| 10 | The <<wcspbrk>> function locates the first occurrence in the |

|---|
| 17 | <[set]> occurs in <[s]>. |
|---|
| 18 | |
|---|
| 19 | PORTABILITY |
