Remove a string from a file. - Butilka - 25.07.2010

Does anybody know how to remove a string from file?
For example:
I got a file text.ini and there are such lines
Код:
25|7|2010|127.0.0.1
25|7|2010|127.0.0.2
25|7|2010|127.0.0.3
25|7|2010|127.0.0.4
A string containing the IP 127.0.0.3 should be removed and file should be saved
Код:
25|7|2010|127.0.0.1
25|7|2010|127.0.0.2
25|7|2010|127.0.0.4

    handle = fopen(filename,io_read);
    format(str,sizeof(str),"%s.part",filename);
    ftmp = fopen(str,io_write);
    while(fread(handle,string))
        if(strfind(string,removed) == -1)
            fwrite(ftmp,string);
    fclose(handle);
    fclose(ftmp);
    handle = fopen(filename,io_write);
    ftmp = fopen(str,io_read);
    while(fread(ftmp,string))
        fwrite(handle,string);
    fclose(handle);
    fclose(ftmp);
    return fremove(str);
}
