wcpncpy

Name

wcpncpy -- copy a fixed-size string of wide characters, returning a pointer to its end

Synopsis

#include <wchar.h>

wchar_t * wcpncpy(wchar_t * dest, const wchar_t * src, size_t n);

Description

wcpncpy() is the wide-character equivalent of stpncpy(). It copies at most n wide characters from the wide-character string src, including the terminating null wide character code, to the array dest. Exactly n wide characters are written at dest. If the length wcslen()(src) is smaller than n, the remaining wide characters in the array dest are filled with null wide character codes. If the length wcslen()(src) is greater than or equal to n, the string dest will not be terminated with a null wide character code.

The strings may not overlap.

The programmer shall ensure that there is room for at least n wide characters at dest.

Return Value

wcpncpy() returns a pointer to the wide character one past the last non-null wide character written.
