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.
