dat_rmr_free(3DAT) Direct Access Transport Library Functions dat_rmr_free(3DAT)
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.
