[Gtkwave-users] Finding edges of specific signal in FST

[Roman P. <ri...@gm...>]

Hi all,
Is there any documentation for FST API?

I need to find edges for specific signals in FST.  What is the best way to
do it?
I'm looking into fstapi.h, looks like there are two ways to read signal
values:

- fstReaderGetValueFromHandleAtTime
I guess this one returns value at specific time, but how can I find time
where value changed?

- fstReaderIterBlocks
This one seem to be an iterator over all value changes for all signals in
waveform?

Is there a way to restrict iteration for specific signals?
Is there a way to start iteration from specific point in time?

Thanks,
Roman
