Printing to stout inside a Squeak plugin class

I wish to print some debugging info to stdout when calling a primitive. How can I do this in Squeak primitive code?

I am attaching a file I created under platforms/. I will attempt to call these functions from inside a primitive. Stay tuned...

Kindly,
Robert

Re: Printing to stout inside a Squeak plugin class

I tried to define a header file in platforms/Cross/plugins/RSPlugin/sqDebug.h, bt to no avail. mvm says can;t file it. Otherwise, mvm can't find these functions, even if sqDebug.c is being compiked and linked, which I believe it is, but not sure.

How can I print to stdout?

Andalso, if I have to write functions to print, where do I put the header file such that mvm willl properly compile and link sqDebug.c?

I think currently your only option is to use the #cCode: method. Something
like this:

| variableToPrint |
<var: #variableToPrint type: #'unsigned int'>
variableToPrint := 10.
self cCode: 'printf("variableToPrint''s value is %u\n", variableToPrint)'

Thanks Levente! Never used this method before, but it looks promising. I
will try after I get my TNC power supply working: digital packet network
over ham radio. I am building it out.
