From 5457dfcb8174f0ff25a0522050c1d79e710a68df Mon Sep 17 00:00:00 2001 From: Christopher Faylor Date: Tue, 17 Jul 2001 03:41:52 +0000 Subject: * child_info.h: Bump magic number. (class child_info): Add an element. * cygheap.cc (init_cheap): Allocate cygwin heap in shared memory area. (cygheap_fixup_in_child): Map cygwin heap, passed from parent via shared memory into correct address. (cygheap_setup_for_child): New function. * cygheap.h: Declare new functions. * dcrt0.cc (dll_crt0_1): Accomodate new cygheap_fixup_in_child arguments. Avoid protecting subproc_ready unless it is spawn/nowait. * fork.cc (fork_parent): Use new cygheap_setup_for_child function to setup cygwin heap info. Close passed cygheap shared memory handle. * spawn.cc (spawn_guts): Ditto. Also, reorganize to avoid synchronization between parent and child in non-P_OVERLAY case. * sigproc.cc (wait_sig): Only signal subproc_ready when execing. --- winsup/cygwin/cygheap.h | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) (limited to 'winsup/cygwin/cygheap.h') diff --git a/winsup/cygwin/cygheap.h b/winsup/cygwin/cygheap.h index a32085d58..0f7c917a4 100644 --- a/winsup/cygwin/cygheap.h +++ b/winsup/cygwin/cygheap.h @@ -166,9 +166,11 @@ struct init_cygheap extern init_cygheap *cygheap; extern void *cygheap_max; +class child_info; +void __stdcall cygheap_setup_for_child (child_info *ci) __attribute__ ((regparm(1))); +void __stdcall cygheap_fixup_in_child (child_info *, bool); extern "C" { void __stdcall cfree (void *) __attribute__ ((regparm(1))); -void __stdcall cygheap_fixup_in_child (HANDLE, bool); void *__stdcall cmalloc (cygheap_types, DWORD) __attribute__ ((regparm(2))); void *__stdcall crealloc (void *, DWORD) __attribute__ ((regparm(2))); void *__stdcall ccalloc (cygheap_types, DWORD, DWORD) __attribute__ ((regparm(3))); -- cgit v1.2.3
