Use the -l c option to qcc to link against this library. This library is usually included automatically.
The iofunc_attr_unlock() function unlocks the attribute structure attr, allowing other threads in the resource manager to change information.
Use this function in conjunction with iofunc_attr_lock() or iofunc_attr_trylock(); call iofunc_attr_unlock() after you've made modifications to the attribute structure. You must unlock the structure as many times as you locked it.
