Re #320.
We have seen this from buggy backends that present NULL for constraint
string_lists. This is probably illegal behaviour from backends but we
don't want to crash.
h5400 now checks validity of -l, -t, -x and -y and auto selects a supported resolution.
scanimage now shows the full range for -x and -y despite other selections.
This creates temporary strings that correspond to the colon-delimited
username and password that are read from file in `auth_callback()`.
The null-terminated strings are used directly to determine lengths.
If the ICC profile added does not match the colour format of the
image, libpng will abort. This can leave the scanner motors in an
incorrect state and possibly cause permanent damage.
This gets rid of a number of obsoleted macros and replaces RETSIGTYPE
with a void literal which can be assumed for C89 and later.
This changeset was prepared using autoupdate and modified to get rid of
whitespace and doubled [] changes. Changes to acinclude.m4 were added
by hand.
- in some cases atexit() doesn't work with libusb-compat
- all exit() functions are replaced by scanimage_exit()
- scanimage_exit() has a new parameter (exit status)
In the process, simplify processing the device list format: don't copy
the format string for writing \0 into it, just iterate over chunks in
the original string.
Add check for winsock2.h for socket.h replancement. Also, use this
check to add ws2_32 library. Also, switch all winsock.h references
to winsock2.h.
Add check for getuid and getpass; which are not on mingw.
Add a syslog() replacement that is basically a print(). This
is also used by vsyslog() replacement.
Comment out parts of replacement sigprocmask.c on mingw.
To support these configure.in changes, I need to rebuild all
related files with autoconf 2.68 and libtool 2.4. Hand ported
our sane-backend specific changes to newer ltmain.sh.
The following updates were made to all directories but backends.
That still needs work. There are also still some pthread issues
and syslog is missing.
Windows doesn't support SIGHUP or SIGPIPE so make that optional.
Only include socket header files when sys/socket.h is detected.
Use winsock.h on windows.
Only include syslog.h when vsyslog() was detect by configure.
Skip FD_CLOEXEC when not supported by OS (not defined).
Only include sys/ioctl.h on platforms that define it.
