Re: passing args

[D-Man <dsh8290 rit edu>]

I like to write functions such as function_prime as a macro because they are so simple.  That way it doesn't take any runtime to call it.

 | The idea is to pass a structure with these two arguments

 | when you have a function
 | 
 | void function(type1 * arg1, type2 * arg2)
 | {
 |  ....
 | }
 | 
 | 
 | you have to define a second function and a structure :
 | 
 | struct struct_arg1_arg2
 | {
 |    type1 * arg1;
 |    type2 * arg2;
 | };
 | 
 | void function_prime(struct struct_arg1_arg2 * arg)
 | {
 |    function(arg->arg1, arg->arg2);
 | }
 | 
 | to call the function, you do the following :
 | 
 | {
 |    struct struct_arg1_arg2 data;
 |    data->arg1 = arg1;
 |    data->arg2 = arg2;
 |    gtk_timeout_add(interval, function, &data);
 | }
