// Name: Sprintf
//
// Description:
// UINTN Sprintf(OUT CHAR8 *Buffer, IN CHAR8 *Format, IN ...) produces a
// null-terminated ASCII string in the output Buffer. The ASCII string is
// produced by parsing the format string specified by Format. Arguments are
// pulled from the variable argument list based on the contents of the format
// string. The number of ASCII characters in the produced output buffer is
// returned, not including the null-terminator. See notes for format string
// information.
//
// Input:
// OUT CHAR8 *Buffer
// Pointer to a null-terminated output ASCII string buffer. User is
// responsible for allocating the necessary memory resources!
//
// IN CHAR8 *Format
// Pointer to a null-terminated format ASCII string.
//
// IN ...
// Variable argument list which provides the data/variables used within the
// format string.
//
// Output:
// UINTN number of ASCII characters in the produced output buffer, not
// including the null-terminator.
//
// Modified:
//
// Referrals:
// va_start
// Sprintf_va_list
// va_end
//
// Notes:
// Objects inside the format string have the following syntax.
// %[flags][width]type
//
