NonStop Kernel File-System Interface
Applications use procedure calls to access Compaq OSI/TS subdevices and
communicate with remote transport users in an OSI network. Use standard file-
system procedure calls to manage transport connections and transfer data. The
System Procedure Calls Reference Manual contains detailed descriptions of these
calls.
This section describes how your application uses file-system procedures to
perform the following tasks:
•
Open an OSI/TS subdevice
•
Fetch and set subdevice configuration parameters (optional)
•
Request a transport connection with a remote transport entity
•
Define OSI/TS response to a connection request from a remote transport
entity (optional)
•
Request transfer of data
•
Request connection release
•
Close the subdevice
These tasks are included in the following subsections.
Transport Connections and Subdevices
Use standard naming conventions to identify transport connections. OSI/TS
associates each transport connection with a subdevice name of the following
form:
$process.#subdevice
#subdevice refers to a file-system object that is added, using SCF, to the
named TSP process.
All file-system requests that your application uses to manage a transport
connection are configured with the parameters of the subdevice through which
the connection was initiated.
Note. An application running in a C-series system (using at least a C30 version of the
operating system) cannot communicate with a remote TSP process having a six-
character name. Therefore, if a TSP process running in a D-series system may
possibly need to provide services to an application running in a remote C-series
system, the TSP process name must be no longer than five characters (including $).
