RDMA_SET_OPTION(3)					   Librdmacm Programmer's Manual					RDMA_SET_OPTION(3)

NAME

       rdma_set_option - Set communication options for an rdma_cm_id.

SYNOPSIS

       #include <rdma/rdma_cma.h>

       int rdma_set_option (struct rdma_cm_id *id, int level, int optname, void *optval, size_t optlen);

ARGUMENTS

       id	   RDMA identifier.

       level	   Protocol level of the option to set.

       optname	   Name of the option, relative to the level, to set.

       optval	   Reference to the option data.  The data is dependent on the level and optname.

       optlen	   The size of the %optval buffer.

DESCRIPTION

       Sets communication options for an rdma_cm_id.  This call is used to override the default system settings.

RETURN VALUE

       Returns 0 on success, or -1 on error.  If an error occurs, errno will be set to indicate the failure reason.

NOTES

       Option details may be found in the relevent header files.

RDMA_MIGRATE_ID(3)					   Librdmacm Programmer's Manual					RDMA_MIGRATE_ID(3)

NAME

       rdma_migrate_id - Move a communication identifer to a different event channel.

SYNOPSIS

       #include <rdma/rdma_cma.h>

       int rdma_migrate_id (struct rdma_cm_id *id, struct rdma_event_channel *channel);

ARGUMENTS

       id	   An existing communication identifier to migrate.

       channel	   The communication channel that events associated with the allocated rdma_cm_id will be reported on.	May be NULL.

DESCRIPTION

       Migrates a communication identifier to a different event channel.

RETURN VALUE

       Returns 0 on success, or -1 on error.  If an error occurs, errno will be set to indicate the failure reason.

NOTES

       This routine migrates a communication identifier to the specified event channel and moves any pending events associated with the rdma_cm_id
       to the new channel.  Users should not poll for events on the rdma_cm_id's current event channel or invoke other routines on the	rdma_cm_id
       while migrating between channels.  This call will block while there are any unacknowledged events on the current event channel.

       If  the channel parameter is NULL, the specified rdma_cm_id will be placed into synchronous operation mode.  All calls on the id will block
       until the operation completes.
