First of all: this is the wrong group, please ask such questions in
fltk.general. fltk.development is for development of FLTK itself.
To your question: I don't see anything obvious. You mean that only the first
"***..." line appears:

... this one above, but ...

> %s\n",counter, buf.mtype, buf.mtext, buf.message);
... not the output of the line above?
If that's true, I can imagine two possible reasons:
1. Your message is not zero-terminated. Chances are that the printf tries to
output a string, and you access something on the stack that is not accessible.
2. The output is written, but your output stream is buffered, and thus you
don't
see it. Try to add
fflush(stdout);
after the print statement to verify this. If your program would crash later, it
is possible that the buffered output would be discarded.
