NAME
       waffle_feature_test_macros - Macros to control definitions exposed by
       Waffle's	headers

SYNOPSIS
       WAFFLE_API_VERSION
       WAFFLE_API_EXPERIMENTAL

DESCRIPTION
       Waffle's	feature	test macros allow the programmer to control the
       definitions that	are exposed by Waffle's	headers	when a program is
       compiled. Conversely, the macros	allow the programmer to	control	which
       Waffle features a program's source relies on.

       In order	to be effective, a feature test	macro must be defined before
       including any header files. This	can be done either in the compilation
       command (cc -DMACRO=value) or by	defining the macro within the source
       code before including any headers.

   Specification of feature test macro requirements in manual pages
       When a function requires	that a feature test macro be defined, the
       manual page docments it in the SYNOPSIS.	When an	enum or	macro requires
       that a feature test macro be defined, the manual	page documents it
       either in the SYNOPSIS or where the enum	or macro first appears in the
       page.

   List	of feature test	macros
       WAFFLE_API_VERSION (since waffle	1.3)
	   This	macro controls the API version exposed by Waffle's headers.
	   The value ((major <<	8) | minor) exposes the	API of Waffle
	   major.minor.	For example, the value 0x0103 exposes the API of
	   Waffle 1.3. If this macro is	undefined, then	the headers expose the
	   API of Waffle 1.2.

       WAFFLE_API_EXPERIMENTAL
	   This	macro exposes experimental features in Waffle's	headers.
	   Experimental	features may be	altered	or removed without notice and
	   do not belong to Waffle's stable API.
