NAME
       rsm_intr_signal_wait_pollfd - wait for events on a list of file descriptors

SYNOPSIS
       cc [ flag... ] file... -lrsm [ library ... ]
       #include <rsmapi.h>

       int rsm_intr_signal_wait_pollfd(struct pollfd fds[], nfds_t nfds, int timeout, int *numfdsp);

DESCRIPTION
       The rsm_intr_signal_wait_pollfd() function is similar to rsm_intr_signal_wait(3RSM), except that it  allows an application to multiplex I/O
       over various types of file descriptors. Applications can use this function to wait for interrupt signals on RSMAPI segments as well as poll
       for I/O events on other non-RSMAPI file descriptors.

       The  fds  argument  is  an  array  of  pollfd  structures  that correspond to both RSMAPI segments and other file descriptors. The rsm_mem-
       seg_get_pollfd(3RSM) is used to obtain a pollfd structure corresponding to an RSMAPI segment.

       The number of file descriptors that have events is returned in numfdsp. This parameter can be set to NULL if the application is not  inter-
       ested  in  the  number  of  file descriptors that have events. See poll(2) for descriptions of the pollfd structure as well as the nfds and
       timeout parameters.

       It is the application's responsibility to establish the validity of a pollfd structure corresponding to an RSMAPI segment by ensuring  that
       rsm_memseg_release_pollfd(3RSM) has not been called on the segment or that the segment has not been destroyed.

       For file descriptors other than RSMAPI segments, the behavior of rsm_intr_signal_wait_pollfd() is similar to poll().

RETURN VALUES
       Upon  successful completion, rsm_intr_signal_wait_pollfd() returns 0 and the revents member of the pollfd struct corresponding to an RSMAPI
       segment is set to POLLRDNORM, indicating that an interrupt signal for that segment was received. Otherwise, an error value is returned.

       For file descriptors other than RSMAPI segments, the revents member of the pollfd struct is identical to that returned by poll(2).

ERRORS
       The rsm_intr_signal_wait_pollfd() function can return the following errors:

       RSMERR_TIMEOUT		       Timeout has occured.

       RSMERR_BAD_ARGS_ERRORS	       Invalid arguments passed.

       RSMERR_BAD_ADDR		       An argument points to an illegal address.

       RSMERR_INTERRUPTED	       The call was interrupted.

       RSMERR_INSUFFICIENT_MEM	       Insufficient memory.

       RSMERR_INSUFFICIENT_RESOURCES   Insufficient resources.
