Struct CGFunctionCallbacks

Source 
pub struct CGFunctionCallbacks {
    pub version: c_uint,
    pub evaluate: *mut CGFunctionEvaluateCallback,
    pub release_info: *mut CGFunctionReleaseInfoCallback,
}
Expand description

A structure that contains callbacks needed by a CGFunctionRef object.

Fields§

§version: c_uint

The structure version number. For this structure,the version should be 0.

§evaluate: *mut CGFunctionEvaluateCallback

The callback that evaluates the function.

§release_info: *mut CGFunctionReleaseInfoCallback

If non-NULL,the callback used to release the info parameterpassed to CGFunctionCreate.
