#define T_DATA
Old name of RUBY_T_DATA.
rb_warning_category_t
Warning categories.
void rb_exc_raise(VALUE mesg)
Raises an exception in the current thread.

Identical to rb_exc_new_cstr(), except it takes a Ruby's string instead of C's.
#define RBIMPL_ATTR_ERROR(msg)
Wraps (or simulates) __attribute__((error))
VALUE rb_str_new_cstr(const char *ptr)
Identical to rb_str_new(), except it assumes the passed pointer is a pointer to a C string.
static bool RTYPEDDATA_P(VALUE obj)
Checks whether the passed object is RTypedData or RData.
static const struct rb_data_type_struct * RTYPEDDATA_TYPE(VALUE obj)
Queries for the type of given object.
This is the struct that holds necessary info for a struct.
uintptr_t VALUE
Type that represents a Ruby object.
static void Check_Type(VALUE v, enum ruby_value_type t)
Identical to RB_TYPE_P(), except it raises exceptions on predication failure.
static bool RB_TYPE_P(VALUE obj, enum ruby_value_type t)
Queries if the given object is of given type.
ruby_value_type
C-level type of an object.
