Detailed Description

       Globus XIO GRIDFTP Client Driver.

Handles

       An XIO handle with the gridftp client driver can be created with
       globus_xio_handle_create()

       The GridFTP client driver makes use of globus ftp client library.
       globus_xio_register_open() call creates a new ftp client handle (unless one is set on the
       attr passed), establishes connection with the GridFTP server. The contact string must
       contain the scheme, host name, and the resource, optionally it might contain port and
       subject also.

       When the XIO handle is closed, the GridFTP driver will destroy its internal resources and
       the ftp client handle (unless this handle was set on an attr).

Reading/Writing

       The globus_xio_register_read() enforce that the waitforbytes parameter should be one. When
       multiple TCP streams are used between the client and the server, data might not be
       delivered in order. globus_xio_data_descriptor_cntl() can be used to get the offset of the
       data.

       globus_xio_register_write() does not enforce any restriction on the waitforbytes
       parameter.

       In any case, when an error or EOF occurs before the waitforbytes request has been met, the
       outgoing nbytes is set to the amount of data actually read/written before the error or EOF
       occurred.

Environment Variables

       • GLOBUS_XIO_GRIDFTP_DEBUG Available if using a debug build. See globus_debug.h for
         format.
