b7ca8783 | 14 | The Print Library functions provide a simple means to produce formatted output \r |
15 | strings. Many of the output functions use a format string to describe how to \r | |
16 | format the output of variable arguments. The format string consists of normal \r | |
17 | text and argument descriptors. There are no restrictions for how the normal \r | |
c553db4b | 18 | text and argument descriptors can be mixed. The following end of line(EOL) \r |
19 | translations must be performed on the contents of the format string:\r | |
20 | \r | |
21 | - '\\r' is translated to '\\r'\r | |
22 | - '\\r\\n' is translated to '\\r\\n'\r | |
23 | - '\\n' is translated to '\\r\\n' \r | |
24 | - '\\n\\r' is translated to '\\r\\n'\r | |
25 | \r | |
26 | This does not follow the ANSI C standard for sprint(). The format of argument \r | |
27 | descriptors is described below. The ANSI C standard for sprint() has been \r | |
28 | followed for some of the format types, and has not been followed for others. \r | |
29 | The exceptions are noted below.\r | |

b7ca8783 | 40 | - Prefix a plus character to a number. Only valid for types X, x, and d. \r |
41 | If both space and + are specified, then space is ignored.\r | |
42 | - 0\r | |
43 | - Pad with 0 characters to the left of a number. Only valid for types \r | |
44 | X, x, and d.\r | |
45 | - ,\r | |
46 | - Place a comma every 3rd digit of the number. Only valid for type d.\r | |
47 | If 0 is also specified, then 0 is ignored.\r | |
48 | - L, l\r | |
790f3b75 LG |
49 | - The number being printed is size UINT64. Only valid for types X, x, and d.\r |

52 | \r | |
53 | [width]:\r | |
54 | \r | |
55 | - *\r | |
56 | - The width of the field is specified by a UINTN argument in the \r | |
57 | argument list.\r | |
58 | - number\r | |
59 | - The number specified as a decimal value represents the width of \r | |
60 | the field.\r | |
61 | - NOTE: If [width] is not specified, then a field width of 0 is assumed.\r | |
62 | \r | |
63 | [.precision]:\r | |
64 | \r | |
65 | - *\r | |
ad5ecf12 | 66 | - The precision of the field is specified by a UINTN argument in the \r |

73 | type:\r | |
74 | \r | |

79 | using this type too by making sure bits 8..15 of the argument are set to 0.\r | |
80 | - x\r | |
790f3b75 | 81 | - The argument is an unsigned hexadecimal number. The characters used are 0..9 and \r |
c3d4e543 | 82 | A..F. If the flag 'L' is not specified, then the argument is assumed \r |
790f3b75 | 83 | to be size int. This does not follow ANSI C.\r |
b7ca8783 | 84 | - X\r |
790f3b75 | 85 | - The argument is an unsigned hexadecimal number and the number is padded with \r |
52707978 | 86 | zeros. This is equivalent to a format string of "0x". If the flag \r |
790f3b75 | 87 | 'L' is not specified, then the argument is assumed to be size int. \r |
b7ca8783 | 88 | This does not follow ANSI C.\r |
89 | - d\r | |
790f3b75 LG |
90 | - The argument is a signed decimal number. If the flag 'L' is not specified, \r |
91 | then the argument is assumed to be size int. \r | |
9ade4339 QS |
92 | - u\r |

790f3b75 LG |
96 | - The argument is a pointer that is a (VOID *), and it is printed as an \r |
97 | unsigned hexadecimal number The characters used are 0..9 and A..F.\r | |
b7ca8783 | 98 | - a\r |
99 | - The argument is a pointer to an ASCII string. \r | |
100 | This does not follow ANSI C.\r | |
101 | - S, s\r | |
102 | - The argument is a pointer to a Unicode string. \r | |
103 | This does not follow ANSI C.\r | |
104 | - g\r | |
105 | - The argument is a pointer to a GUID structure. The GUID is printed \r | |
106 | in the format XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX. \r | |
107 | This does not follow ANSI C.\r | |
108 | - t\r | |
109 | - The argument is a pointer to an EFI_TIME structure. The time and \r | |
c3d4e543 | 110 | date are printed in the format "mm/dd/yyyy hh:mm" where mm is the \r |
b7ca8783 | 111 | month zero padded, dd is the day zero padded, yyyy is the year zero \r |
112 | padded, hh is the hour zero padded, and mm is minutes zero padded. \r | |
113 | This does not follow ANSI C. \r | |
114 | - r\r | |
115 | - The argument is a RETURN_STATUS value. This value is converted to \r | |
116 | a string following the table below. This does not follow ANSI C. \r | |
