Functions

void caca_draw_line (int x1, int y1, int x2, int y2, char c)

Draw a line on the screen using the given character.

void caca_draw_polyline (int const x[], int const y[], int n, char c)

Draw a polyline on the screen using the given character and coordinate arrays. The first and last points are not connected, so in order to draw a polygon you need to specify the starting point at the end of the list as well.

void caca_draw_thin_line (int x1, int y1, int x2, int y2)

Draw a thin line on the screen, using ASCII art.

void caca_draw_thin_polyline (int const x[], int const y[], int n)

Draw a thin polyline on the screen using the given coordinate arrays and with ASCII art. The first and last points are not connected, so in order to draw a polygon you need to specify the starting point at the end of the list as well.
