template<rsize_t n>

int snprintf_s	(	char(&)	s1[n],
		const char *restrict	format,
			...
	)

This function provides for fomatted output into buffer s while taking into account the size of s.

For statically allocated destination buffers this C++ template function automatically deducts snprintf' size argument n.

Parameters:

[out]	s1	The destination buffer
[in]	format	format string (equal to printf)
[in]	...	variable amount of parameters which are treated according to the specified format string.

Returns:

the number of characters that would have been written (not counting the null byte) had s1 been sufficiently large a negative number in case of an encoding error 0 in case of runtime-constraint violation
