Module Name:

  EfiBind.h

Abstract:

  Processor or Compiler specific defines and types for x64.
  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.
