how does FAR determines resize?

[determin1st]

for example im running FAR in ConEmu which window allows to resize its height and width, detecting of the width change is quite simple - it is reported by ReadConsoleInput windows api function giving WINDOW_BUFFER_SIZE_EVENT. but the height change is not reported that way.

so i was thinking how me, the terminal user should fetch that change. is the FAR uses some ticker-poller or is it there some magic ESC sequence to subscribe to resize?

typedef struct _WINDOW_BUFFER_SIZE_RECORD {
  COORD dwSize;
} WINDOW_BUFFER_SIZE_RECORD;

dwSize is the COORD structure containing X and Y

those i know, but when you resize ConEmu window vertically, it doesnt strike, although FAR changes / redraws itself. there must be another way of detecting window change.

also, the Y is useless in that structure, its always 32766, number of lines that buffer stores

If you need a size of visible (display) part of the window, you can call GetConsoleScreenBufferInfo().
