type GLDEBUGPROC = FunPtr GLDEBUGPROCFunc

A pointer to a debug callback.

type GLDEBUGPROCFunc

Arguments

 = GLenum

source.

-> GLenum

type.

-> GLuint

id.

-> GLenum

severity.

userParam.

-> IO ()

Debug callback.

makeGLDEBUGPROC :: GLDEBUGPROCFunc -> IO (FunPtr GLDEBUGPROCFunc)

The storage associated with the resulting FunPtr has to be released with freeHaskellFunPtr when it is no longer required.
