Use TAPs::OpenGL::Fn::CHECK_GL_ERROR() which is a macro for GFnCheckGLError( __FILE__, __LINE__ ) to printout GL errors that are accumulated due to OpenGL commands.
This function is a no-op function if the TAPs_DEBUG_MODE preprocessor symbol is not defined.
Definition at line 178 of file STAPsGLFns.cpp.

Use TAPs::OpenGL::Fn::CHECK_GL_ERROR_MESSAGE( char * customMessage ) which is a macro for GFnCheckGLError( s ) to printout GL errors that are accumulated due to OpenGL commands.
<customMessage> is a string that can be used to indicate the location or message where the error check occurs.
This function is a no-op function if the TAPs_DEBUG_MODE preprocessor symbol is not defined.
