how is the pointer to a particular function passed in the following code

qsort((void **)lineptr,0,nlines-1,[B][I](int(*)(void*,void*))(numeric?numcmp:strcmp)[/I][/B]);

is it the normal way to pass a pointer to a function to another function i.e. by writing the name of the function after what seems to be the declaration of the function?

Seriously I don't get what you are trying to do here.But...

Definition of qsort:

void qsort( void** , int , int , int(*funptr)(void* , void*) );

Calling it:

qsort( , , , func1); //if func is the function you wanna call ; remember it should match with the prototype of your declaration of function pointer in definition
