Описание:

The iofunc_fdinfo_default() function provides the default handler for the client's iofdinfo() call, which is received as an _IO_FDINFO message by the resource manager.

You can place this function directly into the io_funcs table passed to resmgr_attach(), at the fdinfo position, or you can call iofunc_func_init() to initialize all of the functions to their default values.

The iofunc_fdinfo_default() function calls iofunc_fdinfo() and resmgr_pathname() to do the actual work.

Возвращаемое значение:

-1

Успешное завершение; the resource manager library should return a one-part IOV to the client.

EMSGSIZE

Insufficient space is available in the server's buffer to receive the entire message.
