C Specification[edit]

void glGetPointerv( GLenum pname, void ** params );


Parameters[edit]

pname - Specifies the pointer to be returned. Must be one of GL_DEBUG_CALLBACK_FUNCTION or GL_DEBUG_CALLBACK_USER_PARAM .
params - Returns the pointer value specified by pname .


Description[edit]

 glGetPointerv returns pointer information. pname indicates the pointer to be returned, and params is a pointer to a location in which to place the returned data. The parameters that may be queried include:


GL_DEBUG_CALLBACK_FUNCTION  - Returns the current callback function set with the callback argument of glDebugMessageCallback .
GL_DEBUG_CALLBACK_USER_PARAM  - Returns the user parameter to the current callback function set with the userParam argument of glDebugMessageCallback .


Notes[edit]

 glGetPointerv is available in the OpenGL core profile only if the GL version is 4.3 or later. It is available in the compatibility profile for all GL versions, and accepts additional queries. However, these reference pages document only the core profile.


Errors[edit]

 GL_INVALID_ENUM is generated if pname is not an accepted value.
