working with exec_async

[maxdamage99]

maybe I misunderstood you, but ..

		execute_aCD()
{
    exec_async_checkdone();
}

aExecute_getID()
{
    id = level.sv_dataVar["tech"]["exec_count"];
    level.sv_dataVar["tech"]["exec_count"]++;
    
    return id;
}

aExecute_callback(result, id)
{
    level.exec_buffer[id] = result;
    level notify("aExecute_" + id);
}

aExecute(query)
{
    printf("%\n", query);

    id = aExecute_getID();
    exec_async_create(query, ::aExecute_callback, id);
    
    level waittill("aExecute_" + id);
    result = level.exec_buffer[id];
    
    return result;
}

aExecute_(query)
{
    printf("%\n", query);
    exec_async_create_nosave(query);
} 
	

server init:

		level.sv_dataVar["tech"]["exec_count"] = 0;
level.exec_buffer = []; 
	

call:

		result = aExecute("php somework.php " + arg1 + " " + arg2);
if (!isDefined(result))
{
    //execution error
}

if (result[0] == "ERROR")
{
    //script executed but returned error
} 
	

this is for "undefined" if for some reason the script was not executed:

it helped me with problem:
the script was not executed (lack of RAM in my cases)

all other errors (invalid arguments, wrong args types, etc.) can be processed already in the script itself (.sh, .php etc.)
