Detailed Description¶
The Globus FTP Client library provides a convenient way of accessing files on
remote FTP servers. In addition to supporting the basic FTP protocol, the FTP
Client library supports several security and performance extensions to make
FTP more suitable for Grid applications. These extensions are described in the
Grid FTP Protocol document.
In addition to protocol support for grid applications, the FTP Client library
provides a
plugin architecture for installing application or
grid-specific fault recovery and performance tuning algorithms within the
library. Application writers may then target their code toward the FTP Client
library, and by simply enabling the appropriate plugins, easily tune their
application to run it on a different grid.
All applications which use the Globus FTP Client API must include the header
file
globus_ftp_client.h and activate the GLOBUS_FTP_CLIENT_MODULE
To use the Globus FTP Client API, one must create an
FTP Client handle .
This structure contains context information about FTP operations which are
being executed, a cache of FTP control and data connections, and information
about plugins which are being used. The specifics of the connection caching
and plugins are found in the
Handle Attributes section of this manual.
Once the handle is created, one may begin transferring files or doing other FTP
operations by calling the functions in the
FTP Operations section of
this manual. In addition to whole-file transfers, the API supports partial
file transfers, restarting transfers from a known point, and various FTP
directory management commands. All FTP operations may have a set of
attributes, defined in the
FTP Operation Attributes section, associated
with them to tune various FTP parameters. The data structures and functions
needed to restart a file transfer are described in the
Restart Markers
section of this manual. For operations which require the user to send to or
receive data from an FTP server the must call the functions in the
Reading
and Writing Data section of the manual.
