IBV_QUERY_RT_VALUES_EX(3Libibverbs Programmer's	ManuaIBV_QUERY_RT_VALUES_EX(3)

NAME
       ibv_query_rt_values_ex -	query an RDMA device for some real time	values

SYNOPSIS
       #include	<infiniband/verbs.h>

       int ibv_query_rt_values_ex(struct ibv_context *context,
				  struct ibv_values_ex *values);

DESCRIPTION
       ibv_query_rt_values_ex()	 returns  certain real time values of a	device
       context.	 The argument attr  is	a  pointer  to	an  ibv_device_attr_ex
       struct, as defined in <infiniband/verbs.h>.

       struct ibv_values_ex {
	       uint32_t		    comp_mask;	  /* Compatibility mask	that defines the query/queried fields [in/out] */
	       struct timespec	    raw_clock;	  /* HW	raw clock */
       };

       enum ibv_values_mask {
	       IBV_VALUES_MASK_RAW_CLOCK = 1 <<	0, /* HW raw clock */
       };

RETURN VALUE
       ibv_query_rt_values_ex()	returns	0 on success, or the value of errno on
       failure (which indicates	the failure reason).

NOTES
       This extension verb only	calls the provider, the	provider has to	 query
       this value somehow and mark the queried values in the comp_mask field.
