Hi,

I'm looking into the file ftsamplebank.cpp. It uses OpcodeBase.hpp. When copying the filenames into the string array I see it does:

strings[i].data = csound->Strdup(csound, file);

I'm writing something similar but with plugin.h. I can't access Strdup, do I? What would be the correct way of doing it with plugin.h?

Thanks. Cheers.

If it's not too much trouble that'd be great Victor!

It’s there now: you can use it in an opcode through the csound member:

newstr = csound->strdup(s)

Thanks Victor!

Unfortunately I'm still leaking memory. Could it be from csound->strdup
or because I git pulled? Valgrind has some "lost records" including
strdup but I don't think it's the same strdup. I'll keep testing.

Yeah, today I found the README.md in github. It's of great help.

So, Csound is leaking memory according to valgrind. The following
instrument is showing 104 records definitely lost:

instr 1
    print 42
endin

I don’t know. The strdup is the same as in the other opcode you pointed out.

It might not be in Csound. It could be in the alsa library or somewhere else. In your previous example,
valgrind was pointing to libasound:

==9926== 20 bytes in 1 blocks are possibly lost in loss record 30 of 194

Yes, every lost record mentions libasound.

It wasn't there yesterday while I was trying to access Strdup so it
might be the Ubuntu update this morning (if you think it wasn't the git
pull from the Csound repo).

Btw, csound->strdup works great for me. Thanks again!

No, I don’t think we changed anything in memory allocation lately.
