NAME

       io_uring_cq_has_overflow - returns if there are overflow entries waiting to move to the CQ
       ring

SYNOPSIS

       #include <liburing.h>

       bool io_uring_cq_has_overflow(const struct io_uring *ring);

DESCRIPTION

       The io_uring_cq_has_overflow(3) function  informs  the  application  if  CQ  entries  have
       overflowed   and   are   waiting  to  be  flushed  to  the  CQ  ring.  For  example  using
       io_uring_get_events(3)

NOTES

       Using this function is only valid if the ring has IORING_FEAT_NODROP set, as it's checking
       for  a  flag  set  by  kernels  supporting that feature. For really old kernels that don't
       support this feature, if CQE overflow is experienced the CQEs are lost. If  that  happens,
       the CQ ring overflow offset will get incremented.

RETURN VALUE

       True if there are CQ entries waiting to be flushed to the CQ ring.
