(fhandler_disk_file::rewinddir): Don't close handle if it's NULL. (fhandler_disk_file::closedir): Ditto.
* * child_info.h (child_info::sync): Pass pid and HANDLE rather than using pinfo.Christopher Faylor2005-07-171-1/+6
| | | | | | | | | | | | | | | | | | | | | | | | (child_info::child_info): Accept an argument controlling whether to create proc_subproc. (child_info_spawn::child_info_spawn): Ditto. * sigproc.cc (child_info::child_info): Ditto. (child_info_spawn::child_info_spawn): Ditto. (child_info::sync): Use passed in pid and HANDLE. * fork.cc (fork_parent): Reflect additional arguments required for child_info::sync. * hookapi.cc (hook_or_detect_cygwin): Rename. Change so that NULL 'fn' argument just returns "true", indicating that program uses cygwin1.dll. * spawn.cc (av::win16_exe): New element. * spawn.cc (av::iscygwin): New element. (av::fixup): New function. (spawn_guts): Protect against SEGV. Use fixup function to detect when it is safe to wait for a spawned (as opposed to an execed) program. Reflect changes in child_info::sync arguments. * external.cc (cygwin_internal): Reflect function renaming to hook_or_detect_cygwin. * cygheap.cc (cygheap_fixup_in_child): Close handle after debug fixup has been done to prevent false positives in handle collision. * exceptions.cc (try_to_debug): Notify debugger if already being debugged.
* Eliminate (void) cast on standalone function calls throughout.Christopher Faylor2005-07-061-8/+8
