+\r
+ The Print Library functions provide a simple means to produce formatted output \r
+ strings. Many of the output functions use a format string to describe how to \r
+ format the output of variable arguments. The format string consists of normal \r
+ text and argument descriptors. There are no restrictions for how the normal \r
+ text and argument descriptors can be mixed. A normal text character '\n' must \r
+ always be converted to '\n\r'. This does not follow the ANSI C standard for \r
+ sprint(). The format of argument descriptors is described below. The ANSI C \r
+ standard for sprint() has been followed for some of the format types, and has \r
+ not been followed for others. The exceptions are noted below.\r
+\r
+ %[flags][width][.precision]type\r
+\r
+ [flags]:\r
+ - - \r
+ - The field is left justified. If not flag is not specified, then the \r
+ field is right justified.\r
+ - space \r
+ - Prefix a space character to a number. Only valid for types X, x, and d.\r
+ - + \r
+ - Prefix a plus character to a number. Only valid for types X, x, and d. \r
+ If both space and + are specified, then space is ignored.\r
+ - 0\r
+ - Pad with 0 characters to the left of a number. Only valid for types \r
+ X, x, and d.\r
+ - ,\r
+ - Place a comma every 3rd digit of the number. Only valid for type d.\r
+ If 0 is also specified, then 0 is ignored.\r
+ - L, l\r
+ - The number being printed is a UINT64. Only valid for types X, x, and d.\r
+ If this flag is not specified, then the number being printed is a int.\r
+ - NOTE: All invalid flags are ignored.\r
+\r
+ [width]:\r
+\r
+ - *\r
+ - The width of the field is specified by a UINTN argument in the \r
+ argument list.\r
+ - number\r
+ - The number specified as a decimal value represents the width of \r
+ the field.\r
+ - NOTE: If [width] is not specified, then a field width of 0 is assumed.\r
+\r
+ [.precision]:\r
+\r
+ - *\r
+ - The prevision of the field is specified by a UINTN argument in the \r
+ argument list.\r
+ - number\r
+ - The number specified as a decimal value represents the precision of \r
+ the field.\r
+ - NOTE: If [.precision] is not specified, then a precision of 0 is assumed.\r
+\r
+ type:\r
+\r
+ - %\r
+ - Print a %%.\r
+ - c\r
+ - The argument is a Unicode character. ASCII characters can be printed \r
+ using this type too by making sure bits 8..15 of the argument are set to 0.\r
+ - x\r
+ - The argument is a hexadecimal number. The characters used are 0..9 and \r
+ A..F. If the flag 'L' is not specified, then the argument is assumed \r
+ to be an int. This does not follow ANSI C.\r
+ - X\r
+ - The argument is a hexadecimal number and the number is padded with \r
+ zeros. This is equivalent to a format string of "0x". If the flag \r
+ 'L' is not specified, then the argument is assumed to be an int. \r
+ This does not follow ANSI C.\r
+ - d\r
+ - The argument is a decimal number. If the flag 'L' is not specified, \r
+ then the argument is assumed to be an int. \r
+ - p\r
+ - The argument is a pointer that is a (VOID *), and it is printed as a \r
+ hexadecimal number The characters used are 0..9 and A..F.\r
+ - a\r
+ - The argument is a pointer to an ASCII string. \r
+ This does not follow ANSI C.\r
+ - S, s\r
+ - The argument is a pointer to a Unicode string. \r
+ This does not follow ANSI C.\r
+ - g\r
+ - The argument is a pointer to a GUID structure. The GUID is printed \r
+ in the format XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX. \r
+ This does not follow ANSI C.\r
+ - t\r
+ - The argument is a pointer to an EFI_TIME structure. The time and \r
+ date are printed in the format "mm/dd/yyyy hh:mm" where mm is the \r
+ month zero padded, dd is the day zero padded, yyyy is the year zero \r
+ padded, hh is the hour zero padded, and mm is minutes zero padded. \r
+ This does not follow ANSI C. \r
+ - r\r
+ - The argument is a RETURN_STATUS value. This value is converted to \r
+ a string following the table below. This does not follow ANSI C. \r
+ - RETURN_SUCCESS \r
+ - "Success"\r
