ddi_can_receive_sig(9f)

ddi_can_receive_sig(9F)        Kernel Functions        ddi_can_receive_sig(9F)



NAME
       ddi_can_receive_sig - Test for ability to receive signals

SYNOPSIS
       #include <sys/ddi.h>
       #include <sys/sunddi.h>

       boolean_t ddi_can_receive_sig(void);

INTERFACE LEVEL
       Solaris DDI specific (Solaris DDI).

PARAMETERS
       None.

DESCRIPTION
       The  ddi_can_receive_sig()  function returns a boolean value indicating
       whether the current thread can receive signals sent by kill(2). If  the
       return  value  is  B_FALSE, then the calling thread cannot receive sig‐
       nals, and any call  to  qwait_sig(9F),  cv_wait_sig(9F),  or  cv_timed‐
       wait_sig(9F)  implicitly  becomes  qwait(9F), cv_wait(9F), or cv_timed‐
       wait(9F), respectively. Drivers that can block indefinitely awaiting an
       event  should  use this function to determine if additional means (such
       as timeout(9F)) may be necessary to avoid creating unkillable threads.

RETURN VALUES
       B_FALSE    The calling thread is in a state in which signals cannot  be
                  received.  For  example, the thread is not associated with a
                  user process or is in the midst of exit(2) handling.


       B_TRUE     The calling thread may receive a signal while blocked  on  a
                  condition  variable.  Note that this function does not check
                  to determine  whether  signals  are  blocked  (see  sigproc‐
                  mask(2)).


CONTEXT
       The  ddi_can_receive_sig() function may be called from user, kernel, or
       interrupt context.

SEE ALSO
       close(9E), cv_wait(9F), qwait(9F)
