Exclude funtion name from cflow output

I am trying to use cflow to create a call graph of a C code. I don't want some of the functions to show up in the ouput. How can i do that?



Example code:



f() {

    g();

}



main() {

    f();

}


Let's say I don't want g() to show up in the output.



I think I should use -i ^symbol_class to achieve that, but I am not sure, how to do that.



I tried something like



cflow --omit-arguments --omit-symbol-names --symbol unlikely:omit -i ^omit *.c *.h



To define a new symbol class, which contains exactly what I wanted to exclude, but it seems it is not possible.



For reference:
cflow --version
cflow (GNU cflow) 1.4
