From 893ac8e03c21d246bbfc8d575a227d8c65cfae76 Mon Sep 17 00:00:00 2001 From: Christopher Faylor Date: Sun, 3 Jul 2005 02:40:30 +0000 Subject: Replace valid memory checks with new myfault class "exception handling", almost everywhere. Leave some thread.cc stuff alone for now. * cygtls.h: Kludge some definitions to avoid including a problematic windows header. (_cygtls::_myfault): New entry. (_cygtls::_myfault_errno): Ditto. (_cygtls::fault_guarded): New function. (_cygtls::setup_fault): Ditto. (_cygtls::return_from_fault): Ditto. (_cygtls::clear_fault): Ditto. (myfault): New class. * exceptions.cc (handle_exceptions): Handle case of guarded fault in system routine. * gendef: Add another entry point for setjmp that the compiler doesn't know about and won't complain about. * gentls_offsets: Just include windows.h rather than kludging a HANDLE def. * miscfuncs.cc (check_null_str): Delete. (check_null_empty_str): Ditto. (check_null_empty_str_errno): Ditto. (check_null_str_errno): Ditto. (__check_null_invalid_struct): Ditto. (__check_null_invalid_struct_errno): Ditto. (__check_invalid_read_ptr): Ditto. (__check_invalid_read_ptr_errno): Ditto. (dummytest): New function. (check_iovec_for_read): Delete. (chec_iovec): Rename from check_iovec_for_write. Take a read/write parameter. * tlsoffsets.h: Regenerate. * winsup.h: Remove check_* declarations. (check_iovec_for_read): Delete declaration. Turn into a define instead. (check_iovec_for_write): Ditto. (check_iovec): New declaration. * thread.h: Use ifdef guard name consistent with other header files. --- winsup/cygwin/libc/bsdlib.cc | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'winsup/cygwin/libc/bsdlib.cc') diff --git a/winsup/cygwin/libc/bsdlib.cc b/winsup/cygwin/libc/bsdlib.cc index c25163e2e..48ccc4578 100644 --- a/winsup/cygwin/libc/bsdlib.cc +++ b/winsup/cygwin/libc/bsdlib.cc @@ -248,7 +248,8 @@ getprogname (void) extern "C" void setprogname (const char *newprogname) { - if (!check_null_str_errno (newprogname)) + myfault efault; + if (!efault.faulted (EFAULT)) { /* Per BSD man page, setprogname keeps a pointer to the last path component of the argument.
