Hmm... I added printStatus in 2.6.4.
Don't mind. It is just some debugging stuff.
Maybe I should update the version on the web. :-)

Hi Dirk,
Thanks for the file.
I have replaced it in the StreamDevice src directory, but when I ran
make it gave me this error:
../StreamEpics.cc: In static member function ‘static long int
Stream::report(int)’:
../StreamEpics.cc:356:26: error: ‘class Stream’ has no member named
‘printStatus’
make[2]: *** [StreamEpics.o] Error 1
I tried commenting out the line 356, and got no error - Should I just
remove the line, or do I need to update StreamCore? I am running on
StreamDevice 2.6
Apart from that, with the line 356 commented out, I've changed the
protocol to use %s and I don't get the null character anymore. :)
Cheers,
Isabella

Hi Ralph,
Yes, but with %s the device receives something like:
load_curve 675892112117108115101461161201__160 3870\r\n
You are right. And I think that is a bug.
Dirk
The null character corresponds to the 0 at the end of the
waveform (I've
checked it with small strings)

Have you tried using "%s" for the string output?

Hi All,
I have a device to which I need to send a file path
followed by
a number:
example:
load_curve C:\pulse.txt 3870
The file path is stored in the database as a
waveform of chars.
When I run the protocol stream device sends (what I
think is) a
null terminator after the file path:
device receives:
load_curve C:\pulse.txt\x00 3870
Is there any way of getting rid of the \x00 terminator?
Below I copy my protocol and the database records.
Cheers,
Isabella
I've defined the protocol in stream device as:
load_curve
{
out "load_curve %(\$1)c %(\$2)i";
in "%(\$1:\$2)b";
}
and in the database I have:
record(bo, "DEV:LOAD_CURVE") {
field(DTYP, "stream")
field(OUT, "@my.proto load_curve(DEV:CURVE_FILE,
DEV:VPI)
$(PORT)")
}
record(waveform, "DEV:CURVE_FILE") {
field(DESC, "File path")
field(DTYP, "Soft Channel")
field(NELM, "256")
field(FTVL, "CHAR")
}
