pthread_cond_timedwait not reporting error on bad arg.

[Ivan Mari]

In the code below, the timespec argument to pthread_cond_timedwait() is set
to an invalid value: t_nsec > 999,999,999 so, EINVAL error code should be
returned.

Regards,

Ivan Mari

#include <pthread.h>
#include <unistd.h>
#include <stdio.h>
#include <sys/time.h>
#include <errno.h>


void* start_routine( void* arg );

pthread_cond_t m_cond = PTHREAD_COND_INITIALIZER;

pthread_mutex_t m_lock  = PTHREAD_RECURSIVE_MUTEX_INITIALIZER_NP;

int main()
{
  
  struct timespec t;
  
  t.tv_nsec = 1000000000; /* This value should be in the range 0 < tv_nsec <
999999999 */
  t.tv_sec = 1145259964;

  pthread_mutex_lock( &m_lock );
  
  printf("Entering cond wait \n");
  
  int rv = pthread_cond_timedwait( &m_cond, &m_lock, &t );

  if( rv )
  {
        switch( rv )
        {
                case ETIMEDOUT:
                  printf("Error timeout before receiving signal\n");
                  break;
                
                case EINVAL:
                  printf("Error invalid abstime or mutex or cond\n");
                  break;
                                
                case EPERM:
                  printf("Error thread doesn't own mutex\n");
                  break;
        }

  }

  printf("pthread_cond_wait returned %d\n",rv);
  pthread_mutex_unlock( &m_lock );
  return 0;

  
}
