Function pointers within structures

[thebarslider]

struct com {
char nm[COMMAX];
void (*handler)();
};

How do i call the Function above, i have located the appropiate node of my structure using a name search. Now i want to call the function pointer, which will call a void method. The method name is stored in the struct as follows:

struct com comlist[COMS] =
{
{"LOOK",look},
{"L",look},

etc.......

When u initialize the struct variable with the function names, it stores the address in the respective instances of the structure array. Using an index and the function pointer name will suffice. like this:

comlist[i].handler();

Where 'i' holds the index for the FOUND location of the name. I don't believe u didnt try this before asking!;-)

Chow!

Okay, i have got the function to return the function pointer, but how do i name the function so that it knows it will return a function pointer?

I cannot name it void?

U need the function signature I guess. It should be someting like:

void (*funName(void))(void)

This is a function that will return a function pointer to a function which takes nothing and returns nothing.

I hope u got it!

have fun coding...
