2 | This library parses the INI configuration file.\r | |
3 | \r | |
4 | The INI file format is:\r | |
5 | ================\r | |
6 | [SectionName]\r | |
7 | EntryName=EntryValue\r | |
8 | ================\r | |
9 | \r | |
10 | Where:\r | |
11 | 1) SectionName is an ASCII string. The valid format is [A-Za-z0-9_]+\r | |
12 | 2) EntryName is an ASCII string. The valid format is [A-Za-z0-9_]+\r | |
13 | 3) EntryValue can be:\r | |
14 | 3.1) an ASCII String. The valid format is [A-Za-z0-9_]+\r | |
15 | 3.2) a GUID. The valid format is xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx, where x is [A-Fa-f0-9]\r | |
16 | 3.3) a decimal value. The valid format is [0-9]+\r | |
17 | 3.4) a heximal value. The valid format is 0x[A-Fa-f0-9]+\r | |
18 | 4) '#' or ';' can be used as comment at anywhere.\r | |
19 | 5) TAB(0x20) or SPACE(0x9) can be used as separator.\r | |
20 | 6) LF(\n, 0xA) or CR(\r, 0xD) can be used as line break.\r | |
21 | \r | |
22 | Caution: This module requires additional review when modified.\r | |
23 | This driver will have external input - INI data file.\r | |
24 | \r | |
25 | OpenIniFile(), PreProcessDataFile(), ProfileGetSection(), ProfileGetEntry()\r | |
26 | will receive untrusted input and do basic validation.\r | |
