The cancelation cleanup handler shall be popped from the 12 * cancelation cleanup stack and invoked with the argument arg when: 13 * 14 * (a)- The thread exits (calls pthread_exit()) 15 * (b)- The thread acts upon a cancelation request 16 * (c)- the thread calls pthread_cleanup_pop() with a non-zero execution argument 17 * 18 * Testing (c) 19 * 20 * STEPS: 21 * 1. Create a thread 22 * 2. The thread will push a cleanup handler routine, then pop the cleanup handler routine. 23 * 3. Verify that the cleanup handler was called. 24 * 25 */ 26 27#include <pthread.h> 28#include <stdio.h> 29#include <errno.h> 30#include <unistd.h> 31#include "posixtest.h" 32 33# define CLEANUP_NOTCALLED 0 34# define CLEANUP_CALLED 1 35 36int cleanup_flag; 37 38/* Cleanup handler */ 39void a_cleanup_func(void *flag_val) 40{ 41 cleanup_flag = (long)flag_val; 42 return; 43} 44 45/* Function that the thread executes upon its creation */ 46void *a_thread_func() 47{ 48 pthread_cleanup_push(a_cleanup_func, (void*) CLEANUP_CALLED); 49 pthread_cleanup_pop(1); 50 51 pthread_exit(0); 52 return NULL; 53} 54 55int main() 56{ 57 pthread_t new_th; 58 59 /* Initializing values */ 60 cleanup_flag = CLEANUP_NOTCALLED; 61 62 /* Create a new thread. */ 63 if(pthread_create(&new_th, NULL, a_thread_func, NULL) != 0) 64 { 65 perror("Error creating thread\n"); 66 return PTS_UNRESOLVED; 67 } 68 69 /* Wait for thread to end execution */ 70 if(pthread_join(new_th, NULL) != 0) 71 { 72 perror("Error in pthread_join()\n"); 73 return PTS_UNRESOLVED; 74 } 75 76 /* Check to verify that the cleanup handler was called */ 77 if(cleanup_flag != CLEANUP_CALLED) 78 { 79 printf("Test FAILED: Cleanup handler not called\n"); 80 return PTS_FAIL; 81 } 82 83 printf("Test PASSED\n"); 84 return PTS_PASS; 85} 86 87 88
