mlx_put_pixel()

void mlx_put_pixel	(	mlx_image_t *	image,
		uint32_t	x,
		uint32_t	y,
		uint32_t	color
	)

Sets / puts a pixel onto an image.

NOTE: It is considered undefined behaviour when putting a pixel beyond the bounds of an image.

Parameters

[in]	image	The MLX instance handle.
[in]	x	The X coordinate position.
[in]	y	The Y coordinate position.
[in]	color	The color value to put.
