Description
This section lists generic data types used in the cairo API.
Functions
cairo_destroy_func_t ()
void
(*cairo_destroy_func_t) (void *data);
cairo_destroy_func_t the type of function which is called when a
data element is destroyed. It is passed the pointer to the data
element and should free any memory and resources allocated for it.
Since: 1.0
Types and Values
cairo_bool_t
typedef int cairo_bool_t;
cairo_bool_t is used for boolean values. Returns of type
cairo_bool_t will always be either 0 or 1, but testing against
these values explicitly is not encouraged; just use the
value as a boolean condition.
Since: 1.0
cairo_user_data_key_t
typedef struct {
int unused;
} cairo_user_data_key_t;
cairo_user_data_key_t is used for attaching user data to cairo
data structures. The actual contents of the struct is never used,
and there is no need to initialize the object; only the unique
address of a cairo_data_key_t object is used. Typically, you
would just use the address of a static cairo_data_key_t object.
Since: 1.0
cairo_rectangle_int_t
typedef struct {
int x, y;
int width, height;
} cairo_rectangle_int_t;
A data structure for holding a rectangle with integer coordinates.
Since: 1.10
