#define RBIMPL_ATTR_DIAGNOSE_IF(_, __, ___)
Wraps (or simulates) __attribute__((diagnose_if))
#define RBIMPL_ATTR_FORCEINLINE()
Wraps (or simulates) __forceinline.
#define T_DATA
Old name of RUBY_T_DATA.
rb_warning_category_t
Warning categories.
VALUE rb_exc_new_str(VALUE etype, VALUE str)
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))
#define rb_str_new_cstr(str)
Identical to rb_str_new, except it assumes the passed pointer is a pointer to a C string.
#define inline
Old Visual Studio versions do not support the inline keyword, so we need to define it to be __inline.
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.
ruby_value_type
C-level type of an object.
