TypedData_Wrap_Struct() returns a created Ruby object as a VALUE.
|
||
|
The klass argument is the class for the object.

data_type is a pointer to a const ruby_data_type_t which describes

data_type is a pointer to a const rb_data_type_t which describes
|
||
|
how Ruby should manage the struct.
|
||
|
It is recommended that klass derives from a special class called
|
||
|
Data (rb_cData) but not from Object or other ordinal classes.
|
||
|
If it doesn't, you have to call rb_undef_alloc_func(klass).

ruby_data_type_t is defined like this. Let's take a look at each

Defines a read-only global variable. Works just like

rb_define_variable(), except the defined variable is read-only.

void rb_define_virtual_variable(const char *name, VALUE (*getter)(), void (*setter)()) ::

Defines a virtual variable, whose behavior is defined by a pair of C

functions. The getter function is called when the variable is

The getter function must return the value for the access.

void rb_define_hooked_variable(const char *name, VALUE *var, VALUE (*getter)(), void (*setter)()) ::
|

Defines hooked variable. It's a virtual variable with a C variable.

The getter is called as

Defines a global constant. This is just the same as

Returns the name of the class.

int rb_respond_to(VALUE object, ID id) ::

int rb_respond_to(VALUE obj, ID id) ::
|
||

Returns true if the object responds to the message specified by id.

whereas yielded values can be gotten via argc/argv of the third/fourth

|
arguments.

\[OBSOLETE] VALUE rb_iterate(VALUE (*func1)(), void *arg1, VALUE (*func2)(), void *arg2) ::
|
||
|
\[OBSOLETE] VALUE rb_iterate(VALUE (*func1)(), VALUE arg1, VALUE (*func2)(), VALUE arg2) ::
|
||
|
Calls the function func1, supplying func2 as the block. func1 will be
|
||
|
called with the argument arg1. func2 receives the value from yield as
