  4.

  6.         #include <wchar.h>
  7.         wchar_t *wcspbrk(const wchar_t *<[s]>, const wchar_t *<[set]>);
  8.  
  9. TRAD_SYNOPSIS
  10.         wchar_t *wcspbrk(<[s]>, <[set]>
  11.         const wchar_t *<[s]>;

  13.  
  14. DESCRIPTION
  15.         The <<wcspbrk>> function locates the first occurrence in the
  16.         wide-character string pointed to by <[s]> of any wide-character code
  17.         from the wide-character string pointed to by <[set]>.
  18.  
  19. RETURNS
  20.         Upon successful completion, <<wcspbrk>> returns a pointer to the
  21.         wide-character code or a null pointer if no wide-character code from
  22.         <[set]> occurs in <[s]>.
  23.  
  24. PORTABILITY
  25. <<wcspbrk>> is ISO/IEC 9899/AMD1:1995 (ISO C).
