Re: Playing music using pike and SDL.

Were you not able to get any C code to play through SDL either? Does your SDL library have a mixer compiled in it (I think it is optional)?

managing comport settings in linux
by Henrik Grubbstr�m (Lysator) ＠ Pike (-) developers forum 13 Mar '26

Not a good idea; the design philosophy of Pike is that Pike-level code should never be able to cause memory corruption at C-level. With ioctls there's no way to know what data a specific ioctl wants without reading the documentation for that specific ioctl for that specific OS. ioctls and fcntls are a way for device handlers to hook in APIs that aren't standard across all filedescriptors. / Henrik Grubbström (Lysator) Previous text: >2004-08-17 13:32: >Subject: managing comport settings in linux >-------------------------------------------------------------------- >What would be nice, is a way to define ioctl methods in >Pike.

GTK/GDK on OSX
by H William Wellliver III 07 Jan '18

07 Jan '18

I’m running into some build problems on OSX. It seems that the GTK module assumes that if a system is NT that gdkwin.h is used and otherwise gdkx.h is used. Unfortunately, it seems that on some builds of GTK/GDK for OS X, neither of those is correct and that gdkquartz.h should be used. I’m guessing that some configure tests are needed to determine which of the 3 files is actually present. However a quick look at configure.in leaves me unsure how best to include that. Anyone with more expertise in the GTK module’s inner workings care to weigh in? Bill

Proposal: Create Stdio.Port from systemd-provided socket
by Chris Angelico 22 Nov '17

22 Nov '17

Branch: rosuav/systemd-sockets Currently, you can create a Stdio.Port("stdin") as a means of accepting a socket handed to you as FD 0. However, there's no way to accept a socket given as any other FD, making it impossible to use this for systemd's sockets. Example: $ cat /etc/systemd/system/listendemo.service [Unit] Description=Listen Demo Requires=listendemo.socket [Service] User=rosuav ExecStart=/usr/local/bin/pike /home/rosuav/listendemo.pike WorkingDirectory=/home/rosuav $ cat /etc/systemd/system/listendemo.socket [Socket] ListenStream=123 $ cat listendemo.pike object mainsock = Stdio.Port("systemd", acceptloop); void acceptloop() { while (object sock=mainsock->accept()) { write("Accepted sock: %O\n", sock); sock->write("Stub\n"); sock->close(); } } int main() { write("Main sock: %O\n", mainsock); return -1; } Note that the "User=rosuav" directive means that Pike is run as a non-root user. This spares the application the hassle of managing privileges securely, as it never gets root privileges (assuming, of course, that the only reason it needed root was to bind to a privileged port, which is true for a lot of programs). As with "stdin" mode, the second parameter is optional (blocking vs nonblocking). This won't break on non-systemd systems for two reasons: firstly, all it ever does is query environment variables, and secondly, it does this only if the application requests it explicitly, so you have to actually ask for it. Is this something that would be useful? Feel free to bikeshed the API - it's not in 8.1 yet, so anything can change. ChrisA

Bad function identifier on 8.1
by Stephen R. van den Berg 29 May '17

29 May '17

While trying to use Pike 8.1, I consistently get the following on stderr whenever I run pike: /usr/local/pike/8.1.6/lib/modules/Crypto.pmod/Random.pmod.o:-: Warning: Decode failed: Error while decoding program(/usr/local/pike/8.1.6/lib/modules/Crypto.pmod/Random.pmod:23): Bad function identifier offset for random_string:function(int(0..2147483647) : string(8bit)): 3 != 0 It's not immediately obvious to me how to fix this. Anyone? Or am I the only one seeing this? -- Stephen.
