Detailed Description

XSI STREAMS interface (<stropts.h>)

Provides the STREAMS I/O control interface (a legacy XSI extension). STREAMS is rarely implemented in its entirety; Zephyr provides minimal support for compatibility.

Note

STREAMS is an optional XSI extension to POSIX. Portable applications should avoid relying on it; use BSD sockets instead.
