> What is the type of st_ino? It's not off_t?
The type of st_ino is unsigned long long as defined in sys/stat.h for x86 and
off_t is defined in sys/types.h this way;, quoting:
/* This historical accident means that we had a 32-bit off_t on 32-bit
architectures. */
typedef __kernel_off_t off_t;
There is also a related section in the bionic github repo [1] quoted here:
=========================
This probably belongs in the NDK documentation rather than here, but these are
the known ABI bugs in the 32-bit ABI:
time_t is 32-bit. http://b/5819737. In the 64-bit ABI, time_t is 64-bit.
off_t is 32-bit. There is off64_t, and in newer releases there is
almost-complete support for _FILE_OFFSET_BITS. Unfortunately our stdio
implementation uses 32-bit offsets and -- worse -- function pointers to
functions that use 32-bit offsets, so there's no good way to implement the last
few pieces http://b/24807045. In the 64-bit ABI, off_t is off64_t.
sigset_t is too small on ARM and x86 (but correct on MIPS), so support for
real-time signals is broken. http://b/5828899 In the 64-bit ABI, sigset_t is
the correct size for every architecture.
=========================
I will test your patch on x86 and x86_64 on Android and propose a patch if it
works.
