Type Alias mrb_allocf

pub type mrb_allocf = Option<unsafe extern "C" fn(mrb: *mut mrb_state, arg1: *mut c_void, arg2: usize, ud: *mut c_void) -> *mut c_void>;

Function pointer type of custom allocator used in @see mrb_open_allocf.

The function pointing it must behave similarly as realloc except:

• If ptr is NULL it must allocate new space.
• If s is NULL, ptr must be freed.

See @see mrb_default_allocf for the default implementation.
