Function Documentation

static void cleanup ( void  )

static

Cleanup howm's resources.

Delete all of the windows that have been created, remove button grabs and remove pointer focus.

static void exec_config ( char *  conf_path )

static

Execute the script located at conf_path in order to configure howm.

Parameters

conf_path

The file path to the config file.

uint32_t get_colour

(

char *

colour

)

Converts a hexcode colour into an X11 colourmap pixel.

Parameters

colour

A string of the format "#RRGGBB", that will be interpreted as a colour code.

Returns

An X11 colourmap pixel.

void howm_info

(

void

)

Print debug information about the current state of howm.

This can be parsed by programs such as scripts that will pipe their input into a status bar.

int main	(	int	argc,
		char *	argv[]
	)

The code that glues howm together...

static void setup ( void  )

static

Occurs when howm first starts.

Workspaces are initialised, screen size is determined and atoms are then grabbed.

Atoms are gathered.
