Main Loop 3 GHOSD Library Main LoopRunning an app using Ghosd. #include <ghosd/ghosd.h> void ghosd_main_iterations (Ghosd *ghosd); void ghosd_main_until (Ghosd *ghosd, struct timeval *until); void ghosd_flash (Ghosd *ghosd, int fade_ms, int total_display_ms); int ghosd_get_socket (Ghosd *ghosd); ghosd_main_iterationsvoid ghosd_main_iterations (Ghosd *ghosd); Iterate the main loop on the Ghosd, handling all pending X events. This function does not wait for X events, so it returns immediately unless there are already events pending. ghosd : a Ghosd object. ghosd_main_untilvoid ghosd_main_until (Ghosd *ghosd, struct timeval *until); Efficiently iterate the main loop on the Ghosd, handling all pending X events, until the current time reaches the time specified in until. ghosd : a Ghosd object. until : a pointer to a timeval to update until. ghosd_flashvoid ghosd_flash (Ghosd *ghosd, int fade_ms, int total_display_ms); Fade in a Ghosd, display at full opacity for a while, fade out, and then return. This is easy enough to implement using ghosd_main_until(), but is a a common enough use of Ghosd to make it a builtin. ghosd : a Ghosd object. fade_ms : how long to fade, in milliseconds. total_display_ms : total display time, including fades, in milliseconds. ghosd_get_socketint ghosd_get_socket (Ghosd *ghosd); Get the file descriptor of the Ghosd X socket. When this file descriptor has data available, call ghosd_main_iterations() to process the pending X events. Use this with select()/poll() etc. to multiplex Ghosd with other processing. ghosd : a Ghosd object. Returns : a file descriptor, suitable for use in select() or poll().
