[Openrm-users] Initializing OpenRM

[Luke C. <lu...@ba...>]

Hi Wes,

I have a question regarding the steps necessary to initialize OpenRM
in win32 using RM_PIPE_NOPLATFORM, specifically Page 367 "Overview of
RM Initialization", step 3.

I'm trying to figure out why everything works without me having to set
the OpenGL context using rmPipeSetContext.

These are the steps my code performs;

#1 - Initialize OpenRM
#2 - Create a new pipe
#3 - Use the SDL library to create a new window. Internally SDL
performs wglCreateContext, and wglMakeCurrent. I do not assign the
OpenGL context to the pipe.
#4 - Use rmPipeSetWindow to assign the window handle and dimensions to the pipe.
#5 - Use rmPipeMakeCurrent to make the OpenGL context current.

If in #3 above I don't assign the OpenGL context to the pipe using
rmPipeSetContext, then everything works.
If in #3 above I assign a null pointer as theOpenGL context to the
pipe using rmPipeSetContext, then everything works.
If in #3 above I assign hwnd as the OpenGL context to the pipe using
rmPipeSetContext, then everything works.
If in #3 above I assign hglrc as the OpenGL context to the pipe using
rmPipeSetContext, then I experience intermittent crashes. I'm a little
confused as to why this is.

So it seems that it is not necessary to use rmPipeSetContext with
RM_PIPE_NOPLATFORM, is this correct?
