NAME
dat_rmr_free - destroy an instance of the RMR SYNOPSIS
cc [ flag... ] file... -ldat [ library... ] #include <dat/udat.h> DAT_RETURN dat_rmr_free ( IN DAT_RMR_HANDLE rmr_handle ) PARAMETERS
rmr_handle Handle for an instance of the RMR to be destroyed. DESCRIPTION
The dat_rmr_free() function destroys an instance of the RMR. Use of the handle of the destroyed RMR in any subsequent operation except for the dat_rmr_free() fails. Any remote RDMA operation that uses the destroyed RMR rmr_context, whose Transport-specific request arrived to the local host after the dat_rmr_free() has completed, fails and reports a protection violation. Remote RDMA operation that uses the destroyed RMR rmr_context, whose Transport-specific request arrived to the local host prior to the dat_rmr_free() return, 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. The dat_rmr_free() function is allowed on either bound or unbound RMR. If RMR is bound, dat_rmr_free() unbinds (free HCA TPT and other resources and whatever else binds with length of 0 should do), and then free RMR. RETURN VALUES
DAT_SUCCESS The operation was successful. DAT_INVALID_HANDLE The rmr_handle handle is invalid. ATTRIBUTES

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. ATTRIBUTES
