Subject synchronous event handling on Linux
Author David Rushby <
Page 191 of the IB 6 Beta API Guide says:
isc_wait_for_event() cannot be used in Microsoft Windows
applications or under any other operating system that does
not permit processes to pause. Applications on these
platforms must use asynchronous event handling.

It appears to me that isc_wait_for_event() is not implemented on
Linux, just as it is not implemented on Windows. Is that true?
Wouldn't Linux "permit processes to pause"?

BTW, I know that synchronous event handling can be simulated with
asynchronous event handling; I'm just curious as to why
isc_wait_for_event() is not implemented on Linux.
