Module Name:
EfiBind.h
Abstract:
Processor or Compiler specific defines and types for Intel Itanium(TM).
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.
