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 = 10; /* This value should be in the range 0 tv_nsec
9 */
t.tv_sec = 1145259964;
pthread_mutex_lock( m_lock );

int rv = pthread_cond_timedwait( m_cond, m_lock, t );
