Detailed Description

The core namespace for the C++ interface for the OpenGL initialization functions.

Function Documentation

int glload::GetMajorVersion

(

)

This function retrieves the major GL version number. Only works after LoadFunctions has been called.

int glload::GetMinorVersion

(

)

This function retrieves the minor GL version number. Only works after LoadFunctions has been called.

int glload::IsVersionGEQ	(	int	testMajorVersion,
		int	testMinorVersion
	)

Returns non-zero if the current GL version is greater than or equal to the given version.

glload::LoadTest glload::LoadFunctions

(

)

Loads all of the function pointers available.

Loads function pointers for OpenGL. This function will also load the core OpenGL functions (ie: not in extensions). It will only load the version and profile specified by the current OpenGL context. So if you get a 3.2 compatibility context, then it will load only try to load 3.2 compatibility in addition to any available extensions.

Returns

A sys::LoadTest object that defines whether the loading was successful.

glload::LoadTest glload::LoadFunctions	(	Display *	display,
		int	screen
	)

Loads all of the function pointers available.

Loads function pointers for GLX extensions.

Returns

A sys::LoadTest object that defines whether the loading was successful.

glload::LoadTest glload::LoadFunctions

(

HDC

hdc

)

Loads all of the function pointers available.

Loads function pointers for WGL extensions.

Returns

A sys::LoadTest object that defines whether the loading was successful.
