vfPrintf_s()

int Chusov::String::vfPrintf_s ( ::FILE *restrict  stream, const CHAR_TYPE *restrict  pszFormat, va_list  ap  )

noexcept

Resolves to vfPrintfA_s or to vfPrintfW_s depending on the template parameter.

Template Parameters

CHAR_TYPE

is a template parameter specifying a type of strings the template specialization is to work with. That is CHAR_TYPE=char for multibyte strings in the current locale or CHAR_TYPE=wchar_t for wide strings. The corresponding functions, wrapped over by the template specializations, are vfPrintfA_s and vfPrintfW_s.

Parameters

[in]	stream	is a stream descriptor where the formatted string is flushed out.
[in]	pszFormat	is a zero-terminated formatting string.
[in]	ap	is a list of additional parameters corresponding to pszFormat.

Returns

On success the function returns a number of characters of the output not counting the terminating zero. If an output, encoding or runtime constraint violation error occurs the function returns a negative value.

See vfPrintfA_s and vfPrintfW_s for the details.
