Macro Definition Documentation

#define DEBUG_ENABLE   false

Enable debugging output

#define FFT

(

c

)

(c->is_transient || c->is_floating || c->is_fullscreen)

Checks to see if a client is floating, fullscreen or transient.

#define LENGTH

(

x

)

(unsigned int)(sizeof(x) / sizeof(*x))

Calculates the length of an array.

#define LOG_DEBUG   1

#define log_debug	(		M,
			...
	)		fprintf(stderr, "[DEBUG] (%s:%d) " M "\n", __FILE__, __LINE__, ##__VA_ARGS__)

#define LOG_ERR   4

#define log_err	(		M,
			...
	)		fprintf(stderr, "[ERROR] (%s:%d) " M "\n", __FILE__, __LINE__, ##__VA_ARGS__)

#define LOG_INFO   2

#define log_info	(		M,
			...
	)		fprintf(stderr, "[INFO] (%s:%d) " M "\n", __FILE__, __LINE__, ##__VA_ARGS__)

#define LOG_LEVEL   LOG_DEBUG

How much detail should be logged. A LOG_LEVEL of INFO will log almost everything, LOG_WARN will log warnings and errors and LOG_ERR will log only errors.

LOG_NONE means nothing will be logged.

LOG_DEBUG should be used by developers.

#define LOG_NONE   5

#define LOG_WARN   3

#define log_warn	(		M,
			...
	)		fprintf(stderr, "[WARN] (%s:%d) " M "\n", __FILE__, __LINE__, ##__VA_ARGS__)

#define MAX_FD	(		x,
			y
	)		((x) > (y) ? (x + 1) : (y + 1))

Determine which file descriptor is the largest and add one to it.

#define MOVE_RESIZE_MASK

Value:

(XCB_CONFIG_WINDOW_X | XCB_CONFIG_WINDOW_Y | \
                          XCB_CONFIG_WINDOW_WIDTH | XCB_CONFIG_WINDOW_HEIGHT)

Calculates a mask that can be applied to a window in order to reconfigure a window.

#define UNUSED

(

x

)

(void)(x)

Supresses the unused variable compiler warnings.
