The upc_lock_t type

Synopsis

The type declared is

   
    upc_lock_t               

Description

The type upc_lock_t is an opaque UPC type. upc_lock_t is a shared datatype with incomplete type (as defined in [ISO/IEC00 Sec 6.2.5]). Objects of type upc_lock_t may therefore only be manipulated through pointers. Such objects have two states called locked and unlocked.

Two pointers to that reference the same lock object will compare as equal. The results of applying upc_phaseof(), upc_threadof(), and upc_addrfield() to such pointers are undefined.
