finite_shm_alloc

The finite_shm_alloc function allocates a new shared memory buffer to allow rendering to a FiniteShell.

void finite_shm_alloc(FiniteShell *shell, bool withAlpha)

Parameters

Type	Description
`FiniteShell *shell`	The FiniteShell to allocate memory for.
`bool withAlpha`	Whether or not the window should support alpha channels.

Code Example

finite_log_init(stdout, LOG_LEVEL_DEBUG, true);
shell = finite_shell_init("wayland-0"); // get the device

finite_window_init(shell);

// try and draw
finite_shm_alloc(shell, false);

FiniteColorGroup test = { 0.827, 0.247, 0.286 };
finite_draw_rect(shell, 0,0, 200, 100, &test, NULL);

finite_draw_finish(shell, 200, 100, shell->stride, false);
int state = wl_display_dispatch(shell->display);

while (state != -1) {}
FINITE_LOG("Done.");
finite_draw_cleanup(shell);

Standard Usage

When creating an overlay Developers should not ateempt to set the shared memory buffer (shm) until AFTER calling finite_overlay_set_size_and_position
