Subject	[Cs-dev] more string questions..
	The following segfaults Csound(GetStringChannel()). Am I doing something wrong? int main(int argc, char argv[]) { /Create an instance of Csound/ Csound csound = new Csound ; char csd[] = "example1.csd"; csound->Compile(csd); char* msg; char channel[] = "string"; csound->PerformKsmps(); csound->GetStringChannel("string", msg); csound->Perform(); /delete instance of csound/ delete csound; } I am running a performKsmps first to make sure the channel exists. (btw, when does the first init-pass take place, is it during compile?) My Csound instrument looks like this: chn_S "string", 3 instr 1 chnset "test", "string" endin When I run similar code from Cabbage I get the following problem: 0 0x00007ffff6ef6a50 pthread_spin_lock ../nptl/sysdeps/x86_64/../i386/pthread_spin_lock.c 35 1 0x00007ffff6974d3e csoundGetStringChannel /home/rory/sourcecode/csound-csound6-git/Top/threadsafe.c 173 2 0x00000000004e1ec9 Csound::GetStringChannel /usr/local/include/csound/csound.hpp 760 In Cabbage I only call that function as the end of a k cycle. ------------------------------------------------------------------------------ Managing the Performance of Cloud-Based Applications Take advantage of what the Cloud has to offer - Avoid Common Pitfalls.

	msg does not have any memory, I guess that’s why it segfaults. Try using msg[256] or allocating it dynamically.

	Ok, it seems that I only get the segfault if I try to call GetStringChannel() before a call to performKsmps. When is the first init-pass done? The problem I have in Cabbage persists. It takes me to the following function and seg faults at the call to csoundSpinLock()? I'm on Linux btw. void csoundGetStringChannel(CSOUND csound, const char name, char string) { MYFLT pstring; if (csoundGetChannelPtr(csound, &pstring, name, CSOUND_STRING_CHANNEL \| CSOUND_OUTPUT_CHANNEL) == CSOUND_SUCCESS){ int lock = csoundGetChannelLock(csound, (char) name); csoundSpinLock(lock); strcpy(string, ((STRINGDAT ) pstring)->data); csoundSpinUnLock(lock); } } On 8 February 2014 17:51, Victor Lazzarini wrote: > and the code? > On 8 Feb 2014, at 17:25, Rory Walsh wrote: > >> Makes sense, but I still get a segfault char msg[256]? >> >> #0 __strcpy_sse2_unaligned () >> at ../sysdeps/x86_64/multiarch/strcpy-sse2-unaligned.S:297 >> #1 0x00007ffff7a6cd56 in csoundGetStringChannel (csound=0x609030, >> name=0x40574b "string", string=0x7fffffffdf10 "") >> at /home/rory/sourcecode/csound-csound6-git/Top/threadsafe.c:174 >> #2 0x00000000004052a1 in Csound::GetStringChannel (this=0x609010, >> name=0x40574b "string", string=0x7fffffffdf10 "") >> at /usr/local/include/csound/csound.hpp:760 >> #3 0x00000000004037c2 in main (argc=1, argv=0x7fffffffe118) at test.cpp:17 >> >> On 8 February 2014 17:13, Victor Lazzarini wrote: >>> msg does not have any memory, I guess that's why it segfaults.

	I fixed it so that it will not crash. But trying to get a string channel before running performKsmps() does not make any sense. There’s nothing to get.

	yes, because I was being ultrasafe and testing the size of the string you tried to copy into, but that will be 0. I changed it, but remember you will need enough memory for your string, otherwise it’ll crash. In GIT now, working.
