Input Flags in Detail
(continued)
GCOM, INC.
RetryOnSignal If RetryOnSignal is set, dlpi_rcv() retries the getmsg
call when a system call is interrupted. Otherwise,
DLPIAPI_EINTR is returned.
If a putmsg is interrupted with a signal, the putmsg is
retried independent of the setting of the RetryOnSignal
flag.
UNIX signals may interrupt most system calls,
including getmsg (see the EINTR signal defined in
dlpiapi.h). If your application is using signals, your
application may need to control how dlpi_rcv() reacts
when getmsg is interrupted with a signal.

For your application to receive a U-frame event code
(XID, TEST or unnumbered information U-frame), the
