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.
