To send a command to VolServ, the client has to create a 
command handle in which the request and its status is kept. The 
command handle holds the information needed for the VolServ 
API to process the command. The information in the command 
handle is general for all commands (e.g., priority, time-out 
values). Most fields are defaulted to values that can be 
overridden by the client.

Each command has one entry point - a call of the form: 

VSCMD_

Each command accepts the command handle and a variable 
length argument list with parameter name and value pairs. Each 
parameter name and value pair specifies a command option and 
its corresponding value.

The options are divided into two parts: the general command 
options and the command-specific options. The general 
command options are fields contained in all requests (e.g., 
priority). The specific command options are fields particular to 
that type of request (e.g., archive name for the archive vary 
command). A specific command option may not be unique to 
one command, it can be used in several different commands. 
Each command call returns a boolean value that indicates its 
success or failure.
