18 IN DAT_LMR_HANDLE lmr_handle
26 \fB\fIlmr_handle:\fR\fR
29 Handle for an instance of LMR to be destroyed.
35 The \fBdat_lmr_free()\fR function destroys an instance of the LMR. The LMR
36 cannot be destroyed if it is in use by an RMR. The operation does not
37 deallocate the memory region or unpin memory on a host.
40 Use of the handle of the destroyed LMR in any subsequent operation except for
41 \fBdat_lmr_free()\fR fails. Any DTO operation that uses the destroyed LMR after
42 the \fBdat_lmr_free()\fR is completed shall fail and report a protection
43 violation. The use of \fIrmr_context\fR of the destroyed LMR by a remote peer
44 for an RDMA DTO results in an error and broken connection on which it was used.
45 Any remote RDMA operation that uses the destroyed LMR rmr_context\fI\fR, whose
46 Transport-specific request arrived to the local host after the
47 \fBdat_lmr_free()\fR has completed, fails and reports a protection violation.
48 Remote RDMA operation that uses the destroyed LMR \fIrmr_context\fR, whose
49 Transport-specific request arrived to the local host prior to the
50 \fBdat_lmr_free()\fR returns, might or might not complete successfully. If it
51 fails, \fBDAT_DTO_ERR_REMOTE_ACCESS\fR is reported in
52 \fBDAT_DTO_COMPLETION_STATUS\fR for the remote RDMA DTO and the connection is
58 \fB\fBDAT_SUCCESS\fR\fR
61 The operation was successful.
67 \fB\fBDAT_INVALID_HANDLE\fR\fR
70 The \fIlmr_handle\fR parameter is invalid.
76 \fB\fBDAT_INVALID_STATE\fR\fR
79 Parameter in an invalid state; LMR is in use by an RMR instance.
