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_im-
port_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 im-
port including closing the command FD.
RETURN VALUE
ibv_import_device() returns a pointer to the allocated RDMA context, or
NULL if the request fails.
