#cairo_device_type_t is used to describe the type of a given device. The devices types are also known as "backends" within cairo.

cairo_device_type_t

Format

An object of class list of length 9.

Details

The device type can be queried with cairo_device_get_type()

The various #cairo_device_t functions can be used with devices of any type, but some backends also provide type-specific functions that must only be called with a device of the appropriate type. These functions have names that begin with <literal>cairo_<emphasis>type</emphasis>_device</literal> such as cairo_xcb_device_debug_cap_xrender_version().

The behavior of calling a type-specific function with a device of the wrong type is undefined.

New entries may be added in future versions.
