* @short_description: Macros for determining the version of Cogl being used
|
|
*
|
|
* Cogl offers a set of macros for checking the version of the library
|
|
* at compile time.
|
|
*
|
|
* Cogl adds version information to both API deprecations and additions;
|
|
* by definining the macros %COGL_VERSION_MIN_REQUIRED and
|
|
* %COGL_VERSION_MAX_ALLOWED, you can specify the range of Cogl versions
|
|
* whose API you want to use. Functions that were deprecated before, or
|
|
* introduced after, this range will trigger compiler warnings. For instance,
|
|
* if we define the following symbols:
|
|
*
|
|
* |[
|
|
* COGL_VERSION_MIN_REQUIRED = COGL_VERSION_1_6
|
|
* COGL_VERSION_MAX_ALLOWED = COGL_VERSION_1_8
|
|
* ]|
|
|
*
|
|
* and we have the following functions annotated in the Cogl headers:
|
|
*
|
|
* |[
|
|
* COGL_DEPRECATED_IN_1_4 void cogl_function_A (void);
|
|
* COGL_DEPRECATED_IN_1_6 void cogl_function_B (void);
|
|
* COGL_AVAILABLE_IN_1_8 void cogl_function_C (void);
|
|
* COGL_AVAILABLE_IN_1_10 void cogl_function_D (void);
|
|
* ]|
|
|
*
|
|
* then any application code using the functions above will get the output:
|
|
*
|
|
* |[
|
|
* cogl_function_A: deprecation warning
|
|
* cogl_function_B: no warning
|
|
* cogl_function_C: no warning
|
|
* cogl_function_D: symbol not available warning
|
|
* ]|
|
|
*
|
|
* It is possible to disable the compiler warnings by defining the macro
|
|
* %COGL_DISABLE_DEPRECATION_WARNINGS before including the cogl.h
|
|
* header.
