AlliedModders - Pass an array to a function

PHP Code:


		
			
public Action Test(client, args)
{
    ArrayList MyArray = new ArrayList(ByteCountToCells(PLATFORM_MAX_PATH));
    MyFunc(MyArray, "sound/hit/", "kevlar");
    // Do something with MyArray and then destroy it to avoid memory leaks
    CloseHandle(MyArray);
}

void MyFunc(ArrayList array, const char[] sPath, const char[] Filtr)
{
    new Handle:dir;

    if ((dir = OpenDirectory(sPath)))
    {
        char name[128];
        char path[PLATFORM_MAX_PATH];
        new FileType:type;

        while (ReadDirEntry(dir, name, sizeof name, type))
        {
            if (type == FileType_File)
            {
                if (StrEqual(name[strlen(name) - 4], ".wav", false) || StrEqual(name[strlen(name) - 4], ".mp3", false))
                {
                    if (StrContains(name, Filtr, false) != -1)
                    {
                        FormatEx(path, sizeof(path), "%s/%s", sPath, name);
                        array.PushString(path);
                    }
                }
            }
        }
        CloseHandle(dir);
    }
    else
        LogError("Failed to open directory: %s", sPath);
}

You also should use newer syntax (old syntax will be unsupported with newer SourcePawn compiler versions):

PHP Code:


		
			
public Action Test(int client, int args)
{
    ArrayList MyArray = new ArrayList(ByteCountToCells(PLATFORM_MAX_PATH));
    MyFunc(MyArray, "sound/hit/", "kevlar"); // How do you pass an array with other variables?
    // Do something with MyArray and then destroy/close it to avoid memory leaks
    MyArray.Close(); // or "delete MyArray;" but that one also sets the variable to null which is extra unnecessary instruction here
    return Plugin_Handled; // this is important in command callbacks so you won't get "Unknown command" error
}

void MyFunc(ArrayList array, const char[] sPath, const char[] Filtr)
{
    DirectoryListing dir;

    if ((dir = OpenDirectory(sPath)))
    {
        char name[128], path[PLATFORM_MAX_PATH];
        FileType type;

        while (dir.GetNext(name, sizeof name, type))
        {
            if (type == FileType_File)
            {
                if (StrEqual(name[strlen(name) - 4], ".wav", false) || StrEqual(name[strlen(name) - 4], ".mp3", false))
                {
                    if (StrContains(name, Filtr, false) != -1)
                    {
                        FormatEx(path, sizeof(path), "%s/%s", sPath, name);
                        array.PushString(path);
                    }
                }
            }
        }
        dir.Close();
    }
    else
        LogError("Failed to open directory: %s", sPath);
