Function table_wrapper 

pub unsafe fn table_wrapper(
    function: TableFunction,
    ptr: *const u8,
    len: usize,
    out_slice: *mut CSlice,
) -> i32

A wrapper for calling table functions from C.

The input record batch is read from the IPC buffer pointed to by ptr and len.

The output iterator is written to out_slice.

The return value is 0 on success, -1 on error. If successful, the record batch is written to the buffer. If failed, the error message is written to the buffer.

Safety

ptr, len, out_slice must point to a valid buffer.
