[Csnd] Callback best practice (was: Trouble with 5.13 double on MAC)

| Subject | [Csnd] Callback best practice (was: Trouble with 5.13 double on MAC) |
I found the cause of my VST plugin crash. It was my message callback function, that I later set with csound->SetMessageCallback(my_callback)
static void my_callback(CSOUND *, int attr, const char *format, va_list valist) {
if (s_debug_file) {
char messageData[256];
vsprintf(messageData, format, valist);
va_end(valist);
fprintf(s_debug_file, "%s", messageData);
}
}
My text buffer, messageData, was too small. When I increased the size from 256 to 1024 the crash disappeared. I can't find any documented size limit anywhere so I wonder if there is a best practice on callbacks. I don't want to use STL strings in the callback if I can avoid them.

So far I have assumed that csound_->Compile is the crashing API call since I only get a few lines of output from csound before the crash. Xcode debugging is not one of my strong skills, but I'll see what I can do.
Anyway, I will check up on some of your suggestions tomorrow and see where that brings me.
I must get to bed now. It's Father's day here tomorrow so I have to be happy and smiling from early morning.
Thanks,
Sigurd

I wasn't sure if it was, I made that change at some point, but I wasn't sure for what version. If it's there, then there is no need.
The jack libs are not loading possibly because of a missing dependency. But if you got the same error when linking to CsoundLib.framework, the csoundlib is looking for opcodes in the wrong place. Maybe OPCODEDIR is set in the system to point to the
CsoundLib64 framework (which is wrong).
If you can identify which API call is crashing csound, it would help.

I think there might be a constant with the longest message string
size. However, if you allocate more, then it's likely to always work.
One thing I think I did in csoundapi_tilde is to check the size of
format and then allocate that with a bit extra for the valist data.
It always worked. You will need to allocate it dynamically, which
might be a good idea anyway.

I try to avoid dynamic allocation in callbacks as well, but I'm probably just hysteric about performance. If there is no guaranteed upper limit of callback string lengths it might be the only valid solution. There is also a function for returning the length of valist (_vscprintf) that could come in handy.
Thanks again, Victor. The plugin is running fine again now.
