NAME
ibv_create_counters , ibv_destroy_counters - Create or destroy a counters handle
SYNOPSIS
#include <infiniband/verbs.h>
struct
ibv_counters *
ibv_create_counters(struct ibv_context *context,
struct ibv_counters_init_attr *init_attr);
int ibv_destroy_counters(struct ibv_counters *counters);
DESCRIPTION
ibv_create_counters () creates a new counters handle for the RDMA device context.
An ibv_counters handle can be attached to a verbs resource (e.g.: QP, WQ, Flow) statically when these are created.
For example attach an ibv_counters statically to a Flow (struct ibv_flow) during creation of a new Flow by calling ibv_create_flow() .
Counters are cleared upon creation and values will be monotonically increasing.
ibv_destroy_counters () releases the counters handle, user should detach the counters object before destroying it.
ARGUMENTS
context
RDMA device context to create the counters on.
init_attr
Is an ibv_counters_init_attr struct, as defined in verbs.h.
init_attr Argument
struct
ibv_counters_init_attr {
int comp_mask;
};
comp_mask
Bitmask specifying what fields in the structure are valid.
RETURN VALUE
ibv_create_counters () returns a pointer to the allocated ibv_counters object, or NULL if the request fails (and sets errno to indicate the failure reason)
ibv_destroy_counters () returns 0 on success, or the value of errno on failure (which indicates the failure reason)
ERRORS
EOPNOTSUPP
ibv_create_counters () is not currently supported on this device (ENOSYS may sometimes be returned by old versions of libibverbs).
|
ENOMEM |
ibv_create_counters () could not create ibv_counters object, not enough memory |
||
|
EINVAL |
invalid parameter supplied ibv_destroy_counters () |
EXAMPLE
An example of use of ibv_counters is shown in ibv_read_counters
