#include <libnbd.h> int nbd_set_handle_name (struct nbd_handle *h, const char *handle_name);
Handles have a name which is unique within the current process. The handle name is used in debug output.
Handle names are normally generated automatically and have the form
"nbd2", etc., but you can optionally use this call to give the handles a name which is meaningful for your application to make debugging output easier to understand.
If the call is successful the function returns
-1 is returned.
Refer to “ERROR HANDLING” in libnbd(3) for how to get further details of the error.
This function first appeared in libnbd 1.0.

#define LIBNBD_HAVE_NBD_SET_HANDLE_NAME 1
nbd_create(3), nbd_get_handle_name(3), libnbd(3).
