An XIO handle with the gsi driver can be created with either globus_xio_handle_create () or globus_xio_server_register_accept ().

If the handle is created with globus_xio_server_register_accept (), the globus_xio_register_open () call will proceed to accept a GSSAPI security context. Upon successful completion of the open, ie after the open callback has been called, the application may proceed to read or write data associated with the GSI session.

If the handle is created with globus_xio_handle_create (), then the XIO handle will implement the client-side (init) of the GSSAPI call sequence and establish a security context with the accepting side indicated by the contact_string passed to globus_xio_register_open ().
