Re: Read/Write waveforms using Channel Access C API

Just to make sure...

You are aware that there are a number of existing tools for reading and writing sets of PVs (PVTable in CS-Studio, MASAR, CASR, BURT and others) and you have found them not being solutions to your problem.

Hi

 

I am working on a tool which reads a list of PVs (some of which are waveforms) and save those PVs values for later loading them. My problem is with the waveform record, is there a way to know the waveform’s size and read each element? The way I am reading PVs is structured where each DBR type (double, long, enum and string for now) has a struct like this:

 

typedef struct {

                chid channel;

                int status;

                struct dbr_ctrl_TYPE info;

                struct dbr_sts_TYPE data;

}

 

Best Regards,

Abdalla.
