Macro Definition Documentation

◆ WLM_GRAPH_REGENERATE_HISTORY_MAX

#define WLM_GRAPH_REGENERATE_HISTORY_MAX 512

Recommended history size for apps implementing regenerate_fn. Apps storing raw values for regeneration can use this as their buffer size. 512 supports up to 4x HiDPI with no bezel (64 suffices for 1x).

Enumeration Type Documentation

◆ wlm_graph_mode_t

enum wlm_graph_mode_t

Sample accumulation mode: method of accumulating samples for display.

Enumerator
WLM_GRAPH_ACCUMULATE_MODE_INDEPENDENT	Each value fills from bottom independently, overlapping to create heat-map colors where multiple values coincide. The peak line shows the maximum value across all categories.
WLM_GRAPH_ACCUMULATE_MODE_STACKED	Values stack cumulatively on top of each other, with each category rendered as a distinct layer. The peak line shows the sum of all values (clamped to 255).

◆ wlm_graph_read_result_t

enum wlm_graph_read_result_t

Return value for stats_read_fn callback.

Enumerator
WLM_GRAPH_READ_ERROR	Error reading stats; sample will be skipped.
WLM_GRAPH_READ_OK	Success; sample filled normally.
WLM_GRAPH_READ_OK_AND_REGENERATE	Success; also regenerate historical samples (scale changed).

Function Documentation

◆ wlm_graph_app_run()

int wlm_graph_app_run	(	int	argc,
		const char **	argv,
		const wlm_graph_app_config_t *	config )

Runs a graph application.

Handles argument parsing, wlclient setup, icon creation, callback registration, main loop, and cleanup. Apps just need to initialize their state and provide a configuration.

Graph state is managed internally by this function.

Parameters

argc	Argument count.
argv	Argument vector.
config	Application configuration.

Returns: EXIT_SUCCESS or EXIT_FAILURE.
