Backend-agnostic graphics-related functions

Function Documentation

c8_beep()

void c8_beep

(

void

)

Play sound.

This function is weak and is overridden by internal/graphics_sdl.c by default. This can also be overridden by the user when compiling without SDL2 support.

c8_deinit_graphics()

void c8_deinit_graphics

(

void

)

Deinitialize graphics system.

This function is weak and is overridden by internal/graphics_sdl.c by default. This can also be overridden by the user when compiling without SDL2 support.

c8_get_pixel()

uint8_t * c8_get_pixel	(	c8_display_t *	display,
		int	x,
		int	y
	)

Get the value of (x,y) from display

Parameters

display	display_t to get pixel from
x	the x value
y	the y value

Returns

pointer to value of (x,y) in display

c8_init_graphics()

uint8_t c8_init_graphics

(

void

)

Initialize graphics system.

This function is weak and is overridden by internal/graphics_sdl.c by default. This can also be overridden by the user when compiling without SDL2 support.

c8_render()

void c8_render	(	c8_display_t *	display,
		int *	colors
	)

Render graphics.

This function is weak and is overridden by internal/graphics_sdl.c by default. This can also be overridden by the user when compiling without SDL2 support.

c8_tick()

int c8_tick

(

int *

key

)

Grab current keypresses and delay execution to match clockspeed.

This function is weak and is overridden by internal/graphics_sdl.c by default. This can also be overridden by the user when compiling without SDL2 support.
