Function obj_txn_begin_write 

#[unsafe(no_mangle)]
pub unsafe extern "C" fn obj_txn_begin_write(
    db: *mut obj_db_t,
    out_txn: *mut *mut obj_write_txn_t,
) -> obj_error_t

Begin a write transaction against db. Acquires the writer slot (subject to the configured busy timeout).

Safety

• db must be a valid handle returned by obj_open* and not yet closed.
• out_txn must be a writable obj_write_txn_t *. On success it is set to a fresh handle; on failure it is set to NULL.
