Readers are // blocked out until all writers are sleeping. // // In the test there are 4 readers for every writer. However, the // native r/w lock severely skews resources toward writers. // // The generic implementation has no preference among readers and writers. // Therefore whichever thread is ready to read or write will gain the lock // with no dependence on whether the predecessor is a reader or writer. // This results in higher throughput in the test program for linux. // // I would encourage all the platform maintainers to run their own tests // so we can decide which implementation to use for production builds. // //----------------------------------------------------------------- inline void pegasus_yield(void) { sched_yield(); } // pthreads cancellation calls inline void disable_cancel(void) { pthread_setcancelstate(PTHREAD_CANCEL_DISABLE, NULL); } inline void enable_cancel(void) { pthread_setcancelstate(PTHREAD_CANCEL_ENABLE, NULL); } inline void pegasus_sleep(int msec) { sleep(msec/1000); } inline static int pegasus_gettimeofday(struct timeval *tv) { return(gettimeofday(tv, NULL)); } inline void exit_thread(PEGASUS_THREAD_RETURN rc) { pthread_exit(rc); } inline PEGASUS_THREAD_TYPE pegasus_thread_self(void) { return(pthread_self()); } // l10n start typedef pthread_key_t PEGASUS_THREAD_KEY_TYPE; inline Uint32 pegasus_key_create(PEGASUS_THREAD_KEY_TYPE * key) { // Note: a destructor is not supported // (because not supported on Windows (?)) return pthread_key_create(key, NULL); } inline Uint32 pegasus_key_delete(PEGASUS_THREAD_KEY_TYPE key) { return pthread_key_delete(key); } inline void * pegasus_get_thread_specific(PEGASUS_THREAD_KEY_TYPE key) { return pthread_getspecific(key); } inline Uint32 pegasus_set_thread_specific(PEGASUS_THREAD_KEY_TYPE key, void * value) { return pthread_setspecific(key, value); } // l10n end inline void destroy_thread(PEGASUS_THREAD_TYPE th, PEGASUS_THREAD_RETURN rc) { pthread_cancel(th); } PEGASUS_NAMESPACE_END #endif // IPCVMS_Include
