2000-09-08 Ross Johnson <rpj@special.ise.canberra.edu.au>
* cancel.c (pthread_cancel): Must get "self" through calling pthread_self() which will ensure a POSIX thread struct is built for non-POSIX threads; return an error if this fails - Ollie Leahy <ollie@mpt.ie> (pthread_setcancelstate): Likewise. (pthread_setcanceltype): Likewise. * misc.c (ptw32_cancelable_wait): Likewise. * private.c (ptw32_tkAssocCreate): Remove unused #if 0 wrapped code. * pthread.h (ptw32_get_exception_services_code): Needed to be forward declared unconditionally. 2000-09-06 Ross Johnson <rpj@special.ise.canberra.edu.au> * cancel.c (pthread_cancel): If called from the main thread "self" would be NULL; get "self" via pthread_self() instead of directly from TLS so that an implicit pthread object is created. * misc.c (pthread_equal): Strengthen test for NULLs.

+ * File: cancel5.c
+ *
+ * Test Synopsis: Test calling pthread_cancel from the main thread
+ * without calling pthread_self() in main.
+ *
+ * Test Method (Validation or Falsification):
+ * -
+ *
+ * Requirements Tested:
+ * -
+ *
+ * Features Tested:
+ * -
+ *
+ * Cases Tested:
+ * -
+ *
+ * Description:
+ * -
+ *
+ * Environment:
+ * -
+ *
+ * Input:
+ * - None.
+ *
+ * Output:
+ * - File name, Line number, and failed expression on failure.
+ * - No output on success.
+ *
+ * Assumptions:
+ * - have working pthread_create, pthread_self, pthread_mutex_lock/unlock
+ * pthread_testcancel, pthread_cancel, pthread_join
+ *
+ * Pass Criteria:
+ * - Process returns zero exit status.
+ *
+ * Fail Criteria:
+ * - Process returns non-zero exit status.
