Описание:

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

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

The iofunc_chmod_default() function calls iofunc_chmod() to do the actual work.

Возвращаемое значение:

EOK

Успешное завершение.

EROFS

An attempt was made to chmod() 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.
