FIOGETASYNC support

[ASR]

Would appreciate if anybody can help on the below issue:

Is FIOGETASYNC supports to determine whether a socket had asynchronous (signal-driven) I/O is enabled or not on hp-ux 11.23 Itanium. I could see that ioctl that are mentioned as "used by ktestio" in the header file /usr/include/sys/ioctl.h.

/*
* ioctl commands used by ktestio so leave in for now */

#define FIOSETASYNC _IOW('f', 124, int) /* set/clear async I/O
signaling */
#define FIOGETASYNC _IOR('f', 123, int) /* arg is set: */
/* to 1, if
process will be
signaled */
/* to 0, if


If FIOGETASYNC is no longer supported, it would be nice to know if there was an alternative.

Thnx
