Can anyone tell me why the following code results in an error saying
too few arguments passed to GetKsmps()? I'm try to create a simple
template for some my students and can't figure why it think GetKsmps
accepts any arguments at all?

#include "csdl.h"

typedef struct _sndWrite {
OPDS h;
MYFLT *outsig;/* output pointer */
MYFLT *insig;/* input */
} sndWrite;

int sndWrite_init(CSOUND *csound, sndWrite *p){
return OK;
}

int sndWrite_process(CSOUND *csound, sndWrite *p)
{
int i;
MYFLT *in = p->insig;
MYFLT *out = p->outsig;

int ksmps = csound->GetKsmps();
for(i=0; i < ksmps; i++){
	out[i] = in[i];
	}
return OK;
}

#define S(x)    sizeof(x)
static OENTRY localops[] = {
{ "sndWrite", S(sndWrite), 4, "a", "a", (SUBR)sndWrite_init, NULL,
(SUBR)sndWrite_process }
};

Hi,

I haven't looked by I suspect since you are using the CSOUND struct,
you would need to pass a pointer to the current CSOUND struct. You
wouldn't need to if you were using the cpp API.

Cheers,
Andrés

It's

csound->GetKsmps(csound).

Thanks guy. Can I ask Victor how you get away with it in some of your
opcodes, and also in the code from your extensions to Csound article?

The extensions article might not be up-to-date as it was written at a  
time
when the API was changing quite quickly. But I'm sure my opcodes and
from others all have to use this.

I'm seeing things today, apart from your article I thought I spotted
some other instances of it. Another look the source over confirms
you're all correct, csound->GetKsmps(csound) it is..
