Enabling Applications for Grid Computing with Globus

7.2. Globus Toolkit data grid low-level API: globus_io

To use this API, you must activate the GLOBUS_IO module in your program:

globus_module_activate(GLOBUS_IO_MODULE)

Note

The complete Globus IO API documentation is available from the Globus project Web site at the following URL:
