Subject: waveform arrays within SNL

Hi

I cannot find an explicit example in regards to accessing the element values in a waveform array from within an SNL sequencer.

Does anybody have experience doing so?

 

Can’t seem to do this:

 

int locations;

assign locations to "{tel}{instr}:{mech}:locations";  // where locations is a waveform record with an integer array.

int locs[4] = {0,300,600,900};

 

        pvGet( locations );

        locs = locations;               // is the declaration for locations (above) correct?

 

error: incompatible types when assigning to type int[4] from type int *

         locs = locations;

 

This fails too:

         locs[0] = locations[0];

 

I guess I’m ignorant in regards to accessing the array values in the record.

 

Also, is it necessary to escape to C in order to update the elements in a waveform string record?

 

Thanks for any advice you have

Al
