Function vmaxget 

unsafe fn vmaxget() -> *mut c_void

Get the current R memory stack watermark.

Use with vmaxset() to restore memory stack state. Memory allocated with R_alloc() between vmaxget() and vmaxset() will be freed when vmaxset() is called.

Example

unsafe {
    let watermark = vmaxget();
    let buf = R_alloc(100, 1);
    // ... use buf ...
    vmaxset(watermark); // frees buf
}
