Function Macro
GObjectDEFINE_BOXED_TYPE
since: 2.26
Description
A convenience macro for defining a new custom boxed type.
Using this macro is the recommended way of defining new custom boxed
types, over calling g_boxed_type_register_static() directly. It defines
a type_name_get_type() function which will return the newly defined
GType, enabling lazy instantiation.
You might start by putting declarations in a header as follows:
#define MY_TYPE_STRUCT my_struct_get_type ()
GType my_struct_get_type (void) G_GNUC_CONST;
MyStruct * my_struct_new (void);
void my_struct_free (MyStruct *self);
MyStruct * my_struct_copy (MyStruct *self);
And then use this macro and define your implementation in the source file as follows:
MyStruct *
my_struct_new (void)
{
// ... your code to allocate a new MyStruct ...
}
void
my_struct_free (MyStruct *self)
{
// ... your code to free a MyStruct ...
}
MyStruct *
my_struct_copy (MyStruct *self)
{
// ... your code return a newly allocated copy of a MyStruct ...
}
G_DEFINE_BOXED_TYPE (MyStruct, my_struct, my_struct_copy, my_struct_free)
void
foo ()
{
MyStruct *ms;
ms = my_struct_new ();
// ... your code ...
my_struct_free (ms);
}
