------- Comment #3 from pinskia at gcc dot gnu dot org 2007-07-31 18:38 -------
Confirmed, reduced a lot:
int zip_find_end_of_central_dir(void *in, long long *len)
{
char buf[256];
int i = 0;
long long filelen;
long long filepos;
int maxread;
int totalread = 0;
int found = 0;
unsigned extra = 0;
filelen = __PHYSFS_platformFileLength(in);
filepos = 0;
maxread = (unsigned) filelen;
while ((totalread < filelen) && (totalread < 65557))
{
extra = *((unsigned *) (&buf[0]));
for (i = maxread - 4; i > 0; i--)
{
if ((buf[i + 0] == 0x50) &&
(buf[i + 1] == 0x4B) &&
(buf[i + 3] == 0x06) )
{
found = 1;
break;
}
}
}
return (!found) ;
}
