Error description

  • 32-bit call to posix_fadvise fails when _LARGE_FILES
    is enabled.
    
    fcntl.h does not contain a posix_fadvise64
    routine. When _LARGE_FILES is enabled off_t will
    be redefined as a 64-bit value "long long."
    So, instead of 32-bit values, 64-bit values
    will be passed to posix_fadvise causing
    unpredictable results.
    

Local fix

Problem summary

  • 32-BIT CALL TO POSIX_FADVISE FAILS WHEN _LARGE_FILES IS ENABLED
    

Problem conclusion

  • When _LARGE_FILES is enabled , use 64-bit wide off64_t data
    type to read in offsets.
