A VERY simple define:

pawn Код:

#define fopen_append(%0) fopen(%0, fexist(%0) ? io_append : io_write)

//Use:
stock Log(text[])
{
    new File:LOG = fopen_append("logs.txt");
    fwrite(LOG, text);
    fwrite(LOG, "\r\n");
    fclose(LOG);
}

And a simple stock:

pawn Код:

stock fappend(file_path[], string[], bool:new_line = true)
{
    new filemode:io_mode = fexist(file_path) ? io_append : io_write;
    new File:IO = fopen(file_path, io_mode);
    if(!IO) return false;
    if(new_line && _:io_mode == 3) if(!fwrite(IO, "\r\n")) return false;
    if(!fwrite(IO, string)) return false;
    fclose(IO);
    return true;
}

//Use:
fappend("MyLogs.txt", "Hello there!");
fappend("MyLogs.txt", "My name is foobar! :D");
fappend("MyLogs.txt", " (Joking)", false);
