Output a vertical line at a given position in text mode.
void __fastcall__ cvlinexy (unsigned char x, unsigned char y, unsigned char length);
The function outputs a vertical line with the given length starting at a given position.
- The character used to draw the vertical line is system dependent. If available, a line drawing character is used. Drawing a line that is partially off screen leads to undefined behaviour.
- The function is only available as fastcall function, so it may only be used in presence of a prototype.
