display

struct x11display_t* display

Reference to x11display_t. Every call to X library needs this parameter.

sys_drawable

uint32_t sys_drawable

X window ID. The ID describes a drawable either of type window, backbuffer or pixmap.

sys_colormap

uint32_t sys_colormap

X window ID. The ID describes a colormap which is associated with the drawable. A colormap is used to map the drawable pixel depth to the screen pixel depth.

lifetime

x11drawable_FREE

#define x11drawable_FREE { 0, 0, 0 }

Static initializer.

x11drawable_INIT

#define x11drawable_INIT( display,
sys_drawable,
sys_colormap ) { display, sys_drawable, sys_colormap }

Static initializer. See x11drawable_t for the description of the parameter.

query

genericcast_x11drawable

x11drawable_t* genericcast_x11drawable( void * drawable )

Casts drawable into pointer to x11drawable_t if that is possible. The first fields of drawable must match the data fields in x11drawable_t.
