<code c> The swapbuffers function is available in the winbgim implementation of BGI graphics. You do not need to include conio.h; just include graphics.h. The function swaps the roles of the current active and the current visual graphics buffers. It is equivalent to these statements:
int oldv = getvisualpage( ); int olda = getactivepage( ); setvisualpage(olda); setactivepage(oldv); See also
getactivepage getvisualpage initwindow setactivepage setvisualpage
no output of example at the moment do not hesitate and add it...
