Initialize a pthread_attr_t object using pthread_attr_init() 14 * 2. Pass the newly created attribute object to pthread_create() 15 * 3. Test that thread is joinable, since using pthread_attr_init() will 16 * set the default detachstate to PTHREAD_CREATE_JOINABLE. 17 * 4. Pthread_detach() to test this. It should 18 * not return errors since the thread should be joinable (non-detached). If it 19 * returns an error, that means that the thread is not joinable, but rather 20 * in a detached state, and the test fails. 21 * 22 */ 23 24 #include <pthread.h> 25 #include <stdio.h> 26 #include <errno.h> 27 #include <unistd.h> 28 #include "posixtest.h" 29 30 #define TIMEOUT 5 /* Timeout value of 5 seconds. */ 31 #define INTHREAD 0 /* Control going to or is already for Thread */ 32 #define INMAIN 1 /* Control going to or is already for Main */ 33 34 int sem1; /* Manual semaphore */ 35 36 void *a_thread_func() 37 { 38 39 /* Indicate to main() that the thread was created. */ 40 sem1 = INTHREAD; 41 42 /* Wait for main to detach change the attribute object and try and detach this thread. 43 * Wait for a timeout value of 10 seconds before timing out if the thread was not able 44 * to be detached. */ 45 sleep(TIMEOUT); 46 47 printf 48 ("Test FAILED: Did not detach the thread, main still waiting for it to end execution.\n"); 49 pthread_exit((void *)PTS_FAIL); 50 return NULL; 51 } 52 53 int main(void) 54 { 55 pthread_t new_th; 56 pthread_attr_t new_attr; 57 int ret_val; 58 59 /* Initializing */ 60 sem1 = INMAIN; 61 if (pthread_attr_init(&new_attr) != 0) { 62 perror("Cannot initialize attribute object\n"); 63 return PTS_UNRESOLVED; 64 } 65 66 /* Create a new thread passing it the new attribute object */ 67 if (pthread_create(&new_th, &new_attr, a_thread_func, NULL) != 0) { 68 perror("Error creating thread\n"); 69 return PTS_UNRESOLVED; 70 } 71 72 /* Wait for thread to indicate that the start routine for the thread has started. */ 73 while (sem1 == INMAIN) 74 sleep(1); 75 76 /* If pthread_detach fails, that means that the test fails as well. */ 77 ret_val = pthread_detach(new_th); 78 79 if (ret_val != 0) { 80 /* Thread is already detached. */ 81 if (ret_val == EINVAL) { 82 printf("Test FAILED\n"); 83 return PTS_FAIL; 84 } 85 /* pthread_detach() failed for another reason. */ 86 else { 87 printf("Error in pthread_detach(), error: %d\n", 88 ret_val); 89 return PTS_UNRESOLVED; 90 } 91 } 92 93 printf("Test PASSED\n"); 94 return PTS_PASS; 95 96 } 97
