ds

Data server

Syntax:

ds &

Options:

None.

Description:

The data server is a process that maintains a shared state among other processes - it's like a global environment. Processes can store or retrieve data using a set of data server library calls. It can be used for many tasks, but specifically can be accessed from the Slinger webserver in support of dynamic HTML. The HTTP server slinger makes use of the data server and the data server library.

Data is stored using variable names that represent buffers of data. All of the variables are global and can be accessed by any process (no attempt at access restriction is made), so only one instance of the variable (name) can exist in the data server.
