Wait for vertical synchronization
void PgWaitVSync( void );
void PgWaitVSyncCx( void *dc );
- dc
- PgWaitVSyncCx() only. A void pointer to any type of draw context. Examples of draw contexts are:
ph
These functions insert a “wait for vertical sync” tag into
the drawstream. The driver waits until a vertical refresh has
started before continuing to render the draw stream.
PgWaitVSync() works on the current
draw context, while you can specify the draw context for PgWaitVSyncCx().
PgSetFillColor(Pg_RED);
PgWaitVSync();
PgDrawIRect(0,0,99,99,Pg_DRAW_FILL);
PgSetFillColor(Pg_BLACK);
PgDrawIRect(9,9,89,89,Pg_DRAW_FILL);
PgFlush(); // Wait for Vsync, then draw 2 rects
