Hi ! I am using Solaris 2.5.1 with APEX 2.4.1 and are trying to port an application to GNAT 3.11p. Has anyone had a problem in GNAT 3.11p how to bind a thread to a lightweight process (LWP)? In APEX we use ada_krn_defs and os_thread. TASK_ATTR_BOUND_HIPRI : ADA_KRN_DEFS.TASK_ATTR_T := ( Prio => Priority'First +1, Flags => OS_Thread.THR_BOUND, Mutex_attr_address => No_Addr, Cond_attr_address => No_Addr); where OS_thread.THR_BOUND : constant := 16#01#; Within every task type we use pragma task_attributes (TASK_ATTR_BOUND_HIPRI'Address); Is it possible to do this in GNAT 3.11p ? Could one use task_info ? ANY SUGGESTION IS WELCOME !! Regards, Lennart Bergstr�m lennart.bergstrom@mailbox.swipnet.se
