- Common declarations and definitions for Standard C Library headers.\r
-\r
- This header consolidates definitions and declarations for compiler specific\r
- features in one place in order to assist in making the remainder of the\r
- library as compiler independent as possible.\r
-\r
- Certain macro and type definitions are required to be provided by several\r
- different headers. In order to avoid having multiple definitions, and the\r
- attendant risk of having the definitions get out of sync, they are defined in\r
- this header.\r
-\r
- Note that MdePkg/Include/Base.h is automatically included and will bring\r
- processor architecture specific definitions along with it.\r
-\r
- Throughout the library, the following macros are used instead of keywords so\r
- that the library can be easily tuned for different compilers.\r
- __inline Defined to the appropriate keyword or not defined.\r
- __func__ Defined to __FUNC__, __FUNCTION__, or NULL as appropriate.\r
- __restrict Defined to nothing for VC++ or to restrict for GCC and C99 compliant compilers.\r
-\r
- This file and its contents are inspired by the <sys/cdefs.h> files in Berkeley\r
- Unix. They have been re-implemented to be specific to the EFI environment.\r
