# libnvmf\_get\_owner\_from\_tid-libnvme3(2)

Get the registry owner of a transport ID

## NAME

libnvmf\_get\_owner\_from\_tid - Get the registry owner of a transport ID

## SYNOPSIS

**int libnvmf\_get\_owner\_from\_tid** **(struct libnvme\_global\_ctx \*ctx** *,* **const struct libnvmf\_tid \*tid** *,* **char \*\*owner** *);*

## ARGUMENTS

- ctx

  Global context

- tid

  Transport ID identifying the connection to check

- owner

  Returned owner, NULL if no matching controller exists or it is unowned

## DESCRIPTION

Resolves the controller, if any, matching *tid* and reports its registry owner. Does not connect, disconnect, or otherwise modify controller state.

When a matching owned controller exists, *owner* is set to a newly allocated string that the caller must **free**. Otherwise, *owner* is set to NULL. A negative errno return indicates the lookup failed; it is never used to report that no owner exists.

See also: **libnvme\_set\_owner** (lib.h) to declare an orchestrator's own identity, and **libnvmf\_registry\_retrieve** (registry.h) to read a live controller's registry entry by device name rather than by TID.

## RETURN

0 on success (check *owner*), negative errno on failure.
