| Module Name: |
| |
| EfiBind.h |
| |
| Abstract: |
| |
| Processor or Compiler specific defines and types for IA-32. |
| We are using the ANSI C 2000 _t type definitions for basic types. |
| This it technically a violation of the coding standard, but they |
| are used to make EfiTypes.h portable. Code other than EfiTypes.h |
| should never use any ANSI C 2000 _t integer types. |
