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.
