YET MORE ANSI FUNCTIONS + TERMINAL DIMENSIONS

I'm working on creating a double screen buffer in C to have greater control of the display on the terminal. In the meantime, more useful functions useful to that end. :)

Show/Hide cursor:
void hide_cursor()
{
  printf("\e[?25l");
}

void show_cursor()
{
  printf("\e[?25h");
}

Draw box-like characters on Linux Terminal:

ASCII characters change from 106 to 121.

printf("%c(0", 0x1b); // Border chars on

printf("%c(B", 0x1b); // border chars off

Get Terminal Dimensions:

#include <sys/ioctl.h>
#include <stdio.h>

struct winsize max;
int get_terminal_dimensions(int *rows, int *columns)
{
//Get dimensions of screen and pass them by value.
  ioctl(0, TIOCGWINSZ , &max);
  *columns = max.ws_col;
  *rows = max.ws_row;
   return 0;
}
