|
|
<<wcscspn>>---get length of a complementary wide substring
|
|
|
|
ANSI_SYNOPSIS
|
|
#include <wchar.h>
|
|
size_t wcscspn(const wchar_t *<[s]>, wchar_t *<[set]>);
|
|
|
|
TRAD_SYNOPSIS
|
|
size_t wcscspn(<[s]>, <[set]>
|
|
const wchar_t *<[s]>;
|
|
const wchar_t *<[set]>;
|
|
|
|
DESCRIPTION
|
|
The <<wcscspn>> function computes the length of the maximum initial
|
|
segment of the wide-character string pointed to by <[s]> which consists
|
|
entirely of wide-character codes not from the wide-character string
|
|
pointed to by <[set]>.
|
|
|
|
RETURNS
|
|
The <<wcscspn>> function returns the length of the initial substring of
|
|
<[s1]>; no return value is reserved to indicate an error.
|
|
|
|

|
|
<<wcscspn>> is ISO/IEC 9899/AMD1:1995 (ISO C).
