struct stat64 problem

[ccfq]

I have a problem with GCC and C.
(under Windows XP, CPU 32-bit Athlon XP, gcc version 3.4.5, mingw special)

Is there some simple way to return the size of a large file (2GB+) without opening it? GCC seems to not understand "struct stat64" (missing in the header "sys/stat.h")

Coding something like:

struct stat64 statbf;

returns a "storage size of 'statbf' isn't known" error.

My lame workaround is to open the large file:

FILE *f;
 uint64_t size;
f = fopen64( name, "rb" );
fseeko64( f, 0L, 2 );
size = ftello64( f );
fclose( f );

but opening just to get the size seems hacky plus it's about 10 times slower than using "struct stat" and statbf.st_size when processing a tree with thousands of files.

Thanks
