* * pinfo.h (_pinfo::set_exit_state): Declare new function.Christopher Faylor2005-01-111-34/+46
| | | | | | | | | | | | | | | | | | | | | | | | | | (pinfo::exit): Move here from _pinfo::exit. * sigproc.cc (child_info::sync): Use new function to set exitcode and process_state. * pinfo.cc (_pinfo::exit): Ditto. (proc_waiter): Ditto. (_pinfo::set_exit_state): Define new function. (_pinfo::dup_proc_pipe): Close handle when there is no parent process around to care about the exit value. * dcrt0.cc (dll_crt0_0): Move subproc_ready synchronization later to make sure that myself is still mapped in parent. (do_exit): Reflect movement to pinfo::exit. (__api_fatal): Ditto. * exceptions.cc (signal_exit): Ditto. * errno.cc (errmap): Map PROC_NOT_FOUND. * init.cc (dll_entry): Release myself before exiting. * sigproc.cc (proc_can_be_signalled): Set errno appropriately. (sig_send): Ditto. Also remove ill-advised test for !myself->sendsig since this is an indication of a process which is still initializating -- it is not an error. (child_info::sync): Don't set exitcode here. Assume that will happen in proc_waiter, if necessary. * spawn.cc (spawn_guts): Delay "wait_for_myself" logic until later. Don't wait at all if the process has already exited. Reflect movement to pinfo::exit.
