Linux is not the standard. Linux somewhat implements the standard.
You can read about the POSIX standard at
http://www.opengroup.org
> For example some definitions are missing ( ITIMER_REAL.)
The relevant page is:
http://www.opengroup.org/onlinepubs/009695399/basedefs/sys/time.h.html
This is part of XSI, ie an extension, not part of the base POSIX
specification. Implementation of this is optional and eCos does not
currently implement this option.
POSIX timers eg timer_create, timer_settimer, etc are implemented.
This might support the functionality your need. If not, you could
implement itimers if you wanted. eCos is open source after all.
