how to implement a function table

[dragondad]

I have a project, which need to implement a function table for multiple thread call, each thread will start with a different function, and the function table should be a good solution, but I can not find the good reference or programming guide for it.
Please help me out, either a sample (working sample) or an URL.
Thanks.

I normally use something like this:

// start with a typedef for the function - all must be the same return/param types
typedef int fn_declaration_type(int, int);

// pre-declare the functions
int entry_fn_one(int, int);
int entry_fn_two(int, int);
int entry_fn_three(int, int);
...etc...

// declare a table
fn_declaration_type fn_table[FN_TABLE_SIZE] = 
{
    entry_fn_one,
    entry_fn_two,
    entry_fn_three,
    ...etc...
};

// implement the functions
int entry_fn_one(int a, int b)
{
    return 0;
}

int entry_fn_two(int a, int b)
{
    return 0;
}

int entry_fn_three(int a, int b)
{
    return 0;
}

...etc...

It's a bit more difficult if you want the functions wrapped in a class, but it is still possible.
