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.
