The dat_srq_free() function destroys an instance of the SRQ. The SRQ
cannot be destroyed if it is in use by an EP.


It is illegal to use the destroyed handle in any consequent
operation.

RETURN VALUES

DAT_SUCCESS
The operation was successful.


DAT_INVALID_HANDLE
The srq_handle argument is an invalid DAT
handle.


DAT_SRQ_IN_USE
The Shared Receive Queue can not be destroyed
because it is in still associated with an EP
instance.

return DAT_INVALID_HANDLE. The Provider should avoid assigning the
used handle as long as possible. Once reassigned the handle is no
longer a handle of a destroyed object.
