# 2.11 \[Guids] Section

The `[Guids]` section of the EDK II INF file is a list of the global GUID C Names that are used by the module, and not already included. These C names are used by the parsing routine to lookup the actual GUID value that is located in the EDK II package DEC files, and then emit a data structure to the module's `AutoGen.c` file.

GUID C names listed in architectural sections must not be listed in common `[Guids]` sections. The architectural section modifier is used as a restriction to mask items from architectures that are not applicable.

This section uses one of the following section definitions:

```
[Guids]
[Guids.common]
[Guids.IA32]
[Guids.X64]
[Guids.EBC]
```

The formats for entries in this section is:

`gEfiGuidCName [ | Feature FlagExpression ] ## Usage comment`

When a `FeatureFlagExpression` is present, if the expression evaluates to `TRUE`, then the GUID entry is valid. If the expression evaluates to `FALSE`, then the EDK II build tools must ignore the entry.

The following is an example of the `[Guids]` section:

```
[Guids]
  gEfiDebugImageInfoTable
  gEfiHobMemoryAllocModuleGuid
```
