Re: Strange error with fopen


I am really  a silly programmer :-)
I use my_time=localtime() to get current time to create directory but when the system is on heavy load my_time changes it values so i create /2004/04/07/18/19/16 directory but open /2004/04/07/18/19/17/636.jpg file. too bad :).
I change my_time=localtime() with memcpy(my_time,localtime(),sizeof(struct tm)).
I could not fount this error without strace thanks a lot for your suggest.
Saluti Carlo!
