|
*
|
|

* type, but after "static", "inline" or "virtual":
|
|
*
|
|
* \code
|
|
* WZ_DECL_DEPRECATED void deprecatedInlineFunctionA() { .. }

* inline WZ_DECL_DEPRECATED bool deprecatedInlineFunctionD() { .. }

|
|
* You can also mark whole structs or classes as deprecated, by inserting the

* WZ_DECL_DEPRECATED macro after the struct/class keyword, but before the

|
* name of the struct/class:
|
