Updating the Border on the Screen

sw_bdr() changes the border information in the window structure. It does not update the screen. If the window is already on the screen, and you want to update the border, call the video border function, v_bdr():

void v_bdr(wnp)

WINDOWPTR wnp;    /* Pointer to displayed window        */

v_bdr() will use the members of the window structure and write the border to the screen.
