fwrite(file [Add 1]?? - kevannkw - 22.03.2015

So i wonder if i can add 1 with "fwrite"?

So let's say i have 0 in the file and i want to add 1, it increases to 1, then if i do the same command again it should add on the 1 that already exist so it makes it 2?

either use some dini system or whatever or something like that:

pawn Код:

new tmp[10];
new File:myfile = fopen("yourfile.txt", io_readwrite);
fread(myfile, tmp);
format(tmp, sizeof(tmp), "%d", strval(tmp) + 1);
fwrite(myfile, tmp);
fclose(myfile);

although this might be the least efficient way

he wrote some message there and might have noticed that what he wrote was wrong or whatever, therefor he replaced it with "deleted" with what he means "just ignore this"

You have to open the file as read-only, read the contents, close the file, open the file as write-only, write the contents and close the file.

pawn Код:

stock AddOneToFile(file[])
{
     new File:handle = fopen(file, io_read), buf[6];

if(handle)
{
    fread(handle, buf);
    number = strval(buf);
    fclose(handle);
    new File:handle = fopen(file, io_write);

    if(handle)
    {
        fwrite(handle, number+1);
        
        fclose(handle);
    }
}

return 1;
}

Mind giving me an Example?
