26 \fB\fIrmr_handle\fR\fR
29 Handle for an instance of the RMR to be destroyed.
35 The \fBdat_rmr_free()\fR function destroys an instance of the RMR.
38 Use of the handle of the destroyed RMR in any subsequent operation except for
39 the \fBdat_rmr_free()\fR fails. Any remote RDMA operation that uses the
40 destroyed RMR \fIrmr_context\fR, whose Transport-specific request arrived to
41 the local host after the \fBdat_rmr_free()\fR has completed, fails and reports
42 a protection violation. Remote RDMA operation that uses the destroyed RMR
43 \fIrmr_context\fR, whose Transport-specific request arrived to the local host
44 prior to the \fBdat_rmr_free()\fR return, might or might not complete
45 successfully. If it fails, \fBDAT_DTO_ERR_REMOTE_ACCESS\fR is reported in
46 \fBDAT_DTO_COMPLETION_STATUS\fR for the remote RDMA DTO and the connection is
50 The \fBdat_rmr_free()\fR function is allowed on either bound or unbound RMR. If
51 RMR is bound, \fBdat_rmr_free()\fR unbinds (free HCA TPT and other resources
52 and whatever else binds with length of 0 should do), and then free RMR.
57 \fB\fBDAT_SUCCESS\fR\fR
60 The operation was successful.
66 \fB\fBDAT_INVALID_HANDLE\fR\fR
69 The \fIrmr_handle\fR handle is invalid.
