glutMainLoop (3) Linux Manual Page

glutMainLoop – The standard GLUT event loop entry point.

Library

OpenGLUT – mainloop

Synopsis

In openglut.h Ft void Fn glutMainLoop void

Description

This is the main driving force for an event-driven OpenGLUT program. It alternates between calling glutMainLoopEvent() to process pending events and then either sleeping or calling your idle function (see glutIdleFunc()).

This function Bf Li
 can Ef
  return, but GLUT’s version of this function never returned. And you must do special things to OpenGLUT to cause OpenGLUT’s version to return.

The cross-reference section for this function’s documentation should ideally contain every callback, but the list would be tediously long and prone to omissions.

Caveats

For OpenGLUT developers’ internal documentation: Runs until the Bf Sy
 ExecState Ef
 changes to  Bf Sy
 GLUT_EXEC_STATE_STOP. Ef
 

Bugs

Talking to other message systems (e.g., network layers) can be a bit bothersome under the GLUT event model.
