 * Test that pthread_condattr_setpshared()
 *
 * If successful, the pthread_condattr_setpshared() function shall return zero;
 * The pthread_condattr_setpshared() function may fail if:
 *   [EINVAL] The new value specified for the attribute is outside the range of legal values
 *            for that attribute.
 *
 *
 * Steps:
 *
 * 1. Pass to pthread_condattr_setpshared() a negative value for 'pshared'
 * 2. It may return EINVAL
 *
