/* $DOC$ $NAME$ ft_PushVid() $CATEGORY$ Video $ONELINER$ Save current video states on internal stack. $SYNTAX$ ft_PushVid() -> $ARGUMENTS$ None $RETURNS$ The current size of the internal stack (i.e. the number of times ft_PushVid() has been called). $DESCRIPTION$ Menus, picklists, browses, and other video-intensive items often require you to save certain video states -- screen image, cursor position, and so forth. Constantly saving and restoring these items can get very tedious. This function attempts to alleviate this problem. When called, it saves the cursor position, color setting, screen image, cursor style, blink setting, scoreboard setting, snow setting, and maximum row and column to a series of static arrays. All that is needed to restore the saved settings is a call to ft_PopVid(). $EXAMPLES$ ft_PushVid() // Save the current video states $SEEALSO$ ft_PopVid() $END$ */ /* $DOC$ $NAME$ ft_PopVid() $CATEGORY$ Video $ONELINER$ Restore previously saved video states. $SYNTAX$ ft_PopVid() -> $ARGUMENTS$ None $RETURNS$ The number of items remaining in the internal stack. $DESCRIPTION$ This is the complementary function to ft_PushVid(). At some time after saving the video states it will probably be necessary to restore them. This is done by restoring the settings from the last call to ft_PushVid(). The number of items on the internal stack is then reduced by one. Note that the use of stack logic means that items on the stack are retrieved in Last In First Out order. $EXAMPLES$ ft_PopVid() // Restore video states $SEEALSO$ ft_PushVid() $END$ */
