Hi, This is a problem with the type of st_size in struct stat. According to The Single UNIX (R) Specification, Version 2, st_size should be type of off_t which is signed on most systems. However, Linux kernel defines it as unsigned long. I have a damanged filesystem. Some files in lost+found are device files and have st_size == 0xffffffff. On i386, glibc converts the kernel st_size to the 64bit off_t. As the result, unsigned 0xffffffff is converted into 64bit signed 0xffffffff, instead of -1. My question is is st_size treated as unsigned long in kernel? Thanks. -- H.J. Lu (hjl@gnu.org)
