What kinda things is this usefull for?

[BAILOPAN]

if you have to ask you don't know ;]

<serious> it's useful for calling arbitrary functions that you do not know the name for.

for example, PHP has this ability:
$x = "myfunction"
$x(); //This will call "myfunction" if it exists

same thing in C:

int myfunc(void);

int (*func)(void) = myfunc;
(*func)();

Does the "callfunc_begin" execute the public fuction in the plugin also?

What? The callfunc_end does the actual execution

[MagicShot]

yeah sorry PM.. thats what i meant but when You execute it it will run what evers in that public command?

i don't really understand you so i'll make an example

plugin1

// other code (plugin_init etc)...

public the_function(paramint, &paramintref, paramstr[])
{
   log_amx("the_function called. paramint = %d, paramintref = %d, paramstr = %s", paramint, paramintref, paramstr);
   paramintref++;
   paramstr[0] = '[';
   return 100;
}

// other code...

plugin2

// in a function
new intVar = 8;
new strVar[] = "(:"
log_amx("Will call the_function in plugin1.amx; the int param is 4, the intrf Param is 8, the str param is ^"(:^"");
callfunc_begin("the_function", "plugin1.amx");
callfunc_push_int(4);
callfunc_push_intrf(intVar);
callfunc_push_str(strVar);
new retVal = callfunc_end();
log_amx("Called it. Return value: %d; the int var is %d and the str var is %s", retVal, intVar, strVar);

The output should be:

Will call the_function in plugin1.amx; the int param is 4, the intrf Param is 8, the str param is "(:"

the_function called. paramint = 4, paramintref = 8, paramstr = (:

Called it. Return value: 100; the int var is 9 and the str var is [:

Not tested tho
