x11windowmap_entry_t

struct x11windowmap_entry_t

Associates Xlib object id (XID) with object pointer.

An <oostore_memindex_t> is included to allow this type of structure to be stored in an index of type tree for faster searching.

Summary

Variables
id	The identification of an object.
object	The pointer to the identified object.

Variables

id

uint32_t id

The identification of an object.

object

struct x11window_t * object

The pointer to the identified object.

x11windowmap_t

struct x11windowmap_t

Stores a set of x11windowmap_entry_t. TODO: This simplified implementation will be replaced by a dynamic index structure.

x11display_t

extension support

queryextensions_x11display

static int queryextensions_x11display( x11display_t * x11disp )

Initializes extension variables of x11display_t. It is expected that memory of all extension variables is set to zero before you call this function.

lifetime

query

screen

test

childprocess_environment

static int childprocess_environment( void * dummy )

Execute this test in child to make changing environment safe. XOpenDisplay has memory leak in case server does not exist.
