Аргументы:

ctp: A pointer to a resmgr_context_t structure that the resource-manager library uses to pass context information between functions.
msg: A pointer to the io_chown_t structure that contains the message that the resource manager received.
ocb: A pointer to the iofunc_ocb_t structure for the Open Control Block that was created when the client opened the resource.

Описание:

The iofunc_chown_default() function implements POSIX semantics for the client's chown() call, which is received as an _IO_CHOWN message by the resource manager.

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

The iofunc_chown_default() function calls iofunc_chown() to do the actual work.

Возвращаемое значение:

EOK: Успешное завершение.
EROFS: An attempt was made to chown on a read-only filesystem.
EACCES: The client doesn't have permissions to do the operation.
EPERM: The group ID or owner ID didn't match.
