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.
