Binding points for active uniform blocks are assigned using glUniformBlockBinding. Each of a program's active uniform blocks has a corresponding uniform buffer binding point. program is the name of a program object for which the command glLinkProgram() has been issued in the past.
If successful, glUniformBlockBinding specifies that program will use the data store of the buffer object bound to the binding point uniformBlockBinding to extract the values of the uniforms in the uniform block identified by uniformBlockIndex.
GL_INVALID_VALUE is generated if uniformBlockIndex is not an active uniform block index of program.
GL_INVALID_VALUE is generated if uniformBlockBinding is greater than or equal to the value of GL_MAX_UNIFORM_BUFFER_BINDINGS.
