How do you pass a char * function as an argument within a function? (Solved)

Question

I am trying to pass the char * function to return the pointer in order to latter create a dynamic char * size. In line 74 I have an incompatible pointer type ‘char * (*)(void).

Answer 1

the warning tells you exactly what it is. It says :
----
" assignment to 'char *' from incompatible pointer type 'char * (*)(void)' "
-----

< newnode->data.somestr > is expecting a data type < char * >. you are passing in <strfun>, which is just a < char*(*)() >, you have to call <strfun>:

--------
newnode->data.somestr = strfun(); // line 74
