Name

swprintf function — Writes formatted data to a wide string

Synopsis

int swprintf(wchar_t* dst, size_t n, const wchar_t* format,  . . . )

The swprintf function is similar to sprintf, except it stores the formatted output in a wide string, dst, and the format is a wide string. Another difference is that n is the maximum number of wide characters (including a terminating null wide character) that can be written to dst.

The return value is the number of wide characters actually stored in dst (not counting the terminating null wide character) or a negative value if the formatted output requires n or more characters (not including the terminating null character).
