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);
