I pass the stream descriptor from a hllc call on a FC_CPTS function code, to an ioctl call [with IFLUSH and FLUSHR attributes]
<call_made>
ret_code = ioctl(stream_function_descriptor from hllc ,
I_FLUSH,
FLUSHR )
</call_made>
This works most of the time, but sporadically results in a typewriter error.
Can somebody suggest why hllc might return a 'bad' file descriptor that results in a typewriter error?
Thanks
