Object Synopsis

program -- object representing an external program


A program object represents an external program, running in such a way that two-way communication makes the program appear to be a simple function in the caller's program. A program object is established via dt_alloc_program(3), and communication is via dt_welcome(3) and dt_converse(3).

The external program must use the published Pipetalk protocol and, at minimum, must send a welcome message when invoked. All other communication occurs in via calls to dt_converse(3).
