[Freeglut-developer] Leaving glutmainloop

[Sharanga D. <sh...@nt...>]

Hi

Is the shutdown logic for when glutmainloop terminates fully functional?

Using the last example with the fullscreen mode app which used to fail, 
I cannot get it to shutdown and display the message "Exit link 1", which 
was the last line in the main function, despite having executed the 
glutSetOption( GLUT_ACTION_ON_WINDOW_CLOSE, 
GLUT_ACTION_GLUTMAINLOOP_RETURNS );

Also, in the freeglut_main.c function I noticed this at line 1126:

     fgDeinitialize( );
A-->if( fgState.ActionOnWindowClose == GLUT_ACTION_EXIT )<--A
         exit( 0 );

If you look at the fgDeinitialize function at line 271 in freglut_init.c

B-->fgState.ActionOnWindowClose = GLUT_ACTION_EXIT;<--B

is executed, which means Line A will always test true and the app will 
terminate.

Commenting out line B causes the terminating statement ( "Exit Link 1" 
)in my fullscreen test app ( attached here again for completeness ) to 
be displayed. However, the app GPFs instead of terminating correctly.

Is this functionality not supposed to work at the moment?

Cheers
Sha
