◆ vsPrintf_s()

int Chusov::String::vsPrintf_s ( CHAR_TYPE *restrict  pDest,
rsize_t  cchDest,
const CHAR_TYPE *restrict  pszFormat,
va_list  ap 
)
noexcept

Resolves to vsPrintfA_s or to vsPrintfW_s depending on the template parameter.

Template Parameters
CHAR_TYPEis 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 vsPrintfA_s and vsPrintfW_s.
Parameters
[out]pDestis a pointer to the output buffer where the converted string is to be written to.
[in]cchDestis a size of the output buffer, in characters, including the terminating zero.
[in]pszFormatis a pointer to a zero terminated string defining how to interpret data, passed as additional parameters, during the construction of the output.
[in]apis a variable argument list containing data used to construct an output string according to the format.
Returns
On success the function returns a number of characters written to the buffer not counting the terminating zero. If an encoding error occurs the function returns a negative value. If any other runtime constraint violation occurred, the function returns 0.

See vsPrintfA_s and vsPrintfW_s for the details.
