ibv_import_device(3)    Libibverbs Programmer's Manual    ibv_import_device(3)

NAME
       ibv_import_device - import a device from a given command FD

SYNOPSIS
              #include <infiniband/verbs.h>

              struct ibv_context *ibv_import_device(int cmd_fd);

DESCRIPTION
       ibv_import_device() returns an ibv_context pointer that is associated
       with the given cmd_fd.

       The cmd_fd is obtained from the ibv_context cmd_fd member, which must
       be dup'd (eg by dup(), SCM_RIGHTS, etc) before being passed to
       ibv_import_device().

       Once the ibv_context usage has been ended ibv_close_device() should be
       called.  This call may cleanup whatever is needed/opposite of the
       import including closing the command FD.

RETURN VALUE
       ibv_import_device() returns a pointer to the allocated RDMA context, or
       NULL if the request fails.
