Routines to manipulate struct RStruct.
RBIMPL
or rbimpl
are implementation details. Don't take them as canon. They could rapidly appear then vanish. The name (path) of this header file is also an implementation detail. Do not expect it to persist at the place it is now. Developers are free to move it anywhere anytime at will. __VA_ARGS__
is always available. We assume C99 for ruby itself but we don't assume languages of extension libraries. They could be written in C++98. Definition in file rstruct.h.
#define RSTRUCT_PTR | ( | st | ) | rb_struct_ptr(st) |
Exists here for backwards compatibility only. You can safely forget about it.
