dat_lmr_free(3DAT) Direct Access Transport Library Functionsdat_lmr_free(3DAT)

NAME
       dat_lmr_free - destroy an instance of the LMR

SYNOPSIS
       cc [ flag... ] file... -ldat [ library... ]
       #include <dat/udat.h>

       DAT_RETURN
	   dat_lmr_free (
	   IN	 DAT_LMR_HANDLE	   lmr_handle
	   )

PARAMETERS
       lmr_handle:     Handle for an instance of LMR to be destroyed.

DESCRIPTION
       The  dat_lmr_free()  function  destroys an instance of the LMR. The LMR
       cannot be destroyed if it is in use by an RMR. The operation  does  not
       deallocate the memory region or unpin memory on a host.

       Use  of	the  handle  of	 the destroyed LMR in any subsequent operation
       except for dat_lmr_free()  fails.  Any  DTO  operation  that  uses  the
       destroyed  LMR  after  the  dat_lmr_free()  is completed shall fail and
       report a protection violation. The use of rmr_context of the  destroyed
       LMR  by	a  remote  peer for an RDMA DTO results in an error and broken
       connection on which it was used. Any remote RDMA	 operation  that  uses
       the destroyed LMR rmr_context, whose Transport-specific request arrived
       to the local host after the dat_lmr_free()  has	completed,  fails  and
       reports	a  protection  violation.  Remote RDMA operation that uses the
       destroyed LMR rmr_context, whose Transport-specific request arrived  to
       the  local host prior to the dat_lmr_free() returns, might or might not
       complete	 successfully.	 If  it	 fails,	 DAT_DTO_ERR_REMOTE_ACCESS  is
       reported	 in  DAT_DTO_COMPLETION_STATUS for the remote RDMA DTO and the
       connection is broken.

RETURN VALUES
       DAT_SUCCESS	       The operation was successful.

       DAT_INVALID_HANDLE      The lmr_handle parameter is invalid.

       DAT_INVALID_STATE       Parameter in an invalid state; LMR is in use by
			       an RMR instance.
