SYNOPSIS

          typedef bool (*mongoc_client_session_with_transaction_cb_t) (
             mongoc_client_session_t *session,
             void *ctx,
             bson_t **reply,
             bson_error_t *error);

       Provide  this callback to mongoc_client_session_with_transaction() <>. The callback should run a sequence

       commit transactions.

PARAMETERS

       • session: A mongoc_client_session_t <>.

       • ctx: A void* set to the the user-provided ctx passed to mongoc_client_session_with_transaction() <>.

       • reply:  An optional location for a bson_t <https://www.mongoc.org/libbson/current/bson_t.html> or NULL.
         The callback should set this if it runs any operations against the server and receives replies.

       • error: A bson_error_t <https://www.mongoc.org/libbson/current/bson_error_t.html>. The  callback  should
         set this if it receives any errors while running operations against the server.
