/* * File: condvar2.c * * Test Synopsis: * - Test timed wait on a CV. * * Test Method (Validation or Falsification): * - Validation * * Requirements Tested: * -  * * Features Tested: * -  * * Cases Tested: * -  * * Description: * - Because the CV is never signaled, we expect the wait to time out. * * Environment: * - * * Input: * - None. * * Output: * - File name, Line number, and failed expression on failure. * - No output on success. * * Assumptions: * -  * * Pass Criteria: * - pthread_cond_timedwait returns ETIMEDOUT. * - Process returns zero exit status. * * Fail Criteria: * - pthread_cond_timedwait does not return ETIMEDOUT. * - Process returns non-zero exit status. */#include "test.h"#include <sys/timeb.h>pthread_cond_t cv;pthread_mutex_t mutex;intmain(){  struct timespec abstime = { 0, 0 };  struct timeb currSysTime;  const DWORD NANOSEC_PER_MILLISEC = 1000000;  int result;  assert(pthread_cond_init(&cv, NULL) == 0);  assert(pthread_mutex_init(&mutex, NULL) == 0);  assert(pthread_mutex_lock(&mutex) == 0);  /* get current system time */  ftime(&currSysTime);  abstime.tv_sec = currSysTime.time;  abstime.tv_nsec = NANOSEC_PER_MILLISEC * currSysTime.millitm;  abstime.tv_sec += 5;  assert(pthread_cond_timedwait(&cv, &mutex, &abstime) == ETIMEDOUT);    assert(pthread_mutex_unlock(&mutex) == 0);  result = pthread_cond_destroy(&cv);  assert(result == 0);  return 0;}
