Function Documentation

int activity

(

int

ms

)

[inline]

Calculates an activity from a given ms.

Parameters:

ms

time in milliseconds

Return values:

0..256

256 for short time, 0 for >5seconds

char * canonicaltime	(	time_t	t,
		char *	buf,
		int	size
	)			[inline]

Format time: <1ms: µs, <1s: ms, <1min: s, <1h: min.

Parameters:

	t	time in os-spec units
	buf	buffer
	size	size of buffer

Returns:

ptr to filled-in buf, or 0 for error (buf too small)

static char* disp_ftime	(	timedisp_t	key,
		cputime_t	t,
		char *	buf,
		int	size
	)			[static]

Format time according to timekey.

Parameters:

	key	timekey
	t	time itself, in os-specific units. If key==TIME_RELLOAD, real value is 1/10th of given one.
	buf	buffer, at least 11 bytes
	size	size of buffer

Returns:

ptr to filled-in buf, or 0 for error (buf too small)

References canonicaltime().

void message	(	const char *	f,
			...
	)

Send a message to the user.

This function opens a window with the message printed in. Later, when the grid-widget is fixed, a status line might be used.

Note:

The message has a limit on its printed length, about 100byte.

static void select_callback	(	dope_event *	ev,
		void *	arg
	)			[static]

Callback for switch button.

Parameters:

arg

a jtop_callback_t type, which win and idx set. win is the window-id, idx is the nr of the row (0..)

References disp_by_nr().

int update_values

(

load_display_t *

disp

)

Update a display.

If new threads appear, the dope-grid is adapted. This is adding new values, and changing the size of the frame.

Precondition:

The caller should hold the disp-lock
