int seconds );
sam_initrpc()
is the initialization routine for the libsamrpc library. It finds
the RPC entry for the StorageTek QFS or Oracle HSM server and creates an RPC
client handle. In essence, this routine sets up the connection to the StorageTek QFS or Oracle HSM host machine,
required for other API calls in the libsamrpc library.
The
sam_initrpc_timeout
provides the additional capability to specify a timeout value for subsequent Oracle HSM
RPC calls. The default timeout value is 25 seconds.
rpchost is the hostname of the StorageTek QFS or Oracle HSM host.
If NULL,
sam_initrpc()
will check for an environment variable named SAMHOST. If such an
environment variable exists, its setting will be taken for the hostname of
the StorageTek QFS or Oracle HSM host, otherwise
the built-in default, samhost, is used.
seconds is the number of seconds used to timeout Oracle HSM RPC calls.
sam_initrpc()
and
sam_initrpc_timeout()
gets the RPC entry (program number) using the program name samfs.
This information (the RPC program name and number), and the hostname, is
used to set up communication with the StorageTek QFS or Oracle HSM RPC API
server process, sam-rpcd, which runs on the StorageTek QFS or Oracle HSM
host machine.
Upon successful completion a value of 0 is returned.
Otherwise, a value of -1 is returned and
errno
is set to indicate the error.
sam_initrpc()
or
sam_initrpc_timeout()
fails if one or more of the following are true:
EADDRNOTAVAILNo RPC entry for the program name samfs could be found.
EINVALThe number of seconds specified in
sam_initrpc_timeout()
is less than the default.
ECANCELEDSetting the timeout value in
sam_initrpc_timeout()
failed.
