Hi,
I need a help in C++ programming
In program - I want to make empty a log file depending upon its size(eg 10Mb)

I'm not too familiar with C++, but I have done PHP... I don't recall a file size function. One way to find it might to just to open the file in append mode, and then get the current file pointer. I *think* youn can do that in C, but like I said, I don't program with it.

Look up the stat() command.
I think something like this will work.



#include <sys/stat.h>
#include <sys/types.h>

main()
{
struct stat sbuf;
stat("yourfilenamehere",&sbuf);
printf("Your file is %d bytes\n" sbuf.st_size);
}
