Named Pipes
On UNIX and on Windows NT, a non-Progress application (such as a C program or commercial software package) can communicate with a Progress application using named pipes.
Named pipes provide a general exchange mechanism for text data. There is no practical limit to the types of data you can exchange using named pipes. Any data you can access as a character string within Progress, you can read or write to a named pipe.
Progress accesses named pipes already created on your UNIX or Windows NT systems. Progress does not create a named pipe itself. Progress treats a named pipe the same way it treats a text file.
To ensure portability, avoid using named pipes; they are only valid on UNIX or Windows NT systems. See the Progress External Program Interfaces manual for more information on named pipes.
