Detailed Description

Stream buffer for external applications.

A appstreambuf is a buffer provides access to the standard input / output of a system call. Embedded in an iostream objects it is possible to read and write to a external application like to a common stream object.

This stream buffer is limited to read only or write only. A bidirectional access is not possible.
