inline void* osg::getGLExtensionFuncPtr

(const char* funcName)

return the address of the specified OpenGL function.

Documentation

return the address of the specified OpenGL function. return NULL if function not supported by OpenGL library. Note, glGLExtensionFuncPtr is declared inline so that the code is compiled localy to the calling code. This should get by Windows dumb implementation of having different GL function ptr's for each library when links to it.
