The __fxstatat() function shall implement the fstatat() function. The behavior of __fxstatat() for values of ver other than _STAT_VER is undefined. See Data Definitions in the architecture specific part of this specification for the correct value of _STAT_VER.
__fxstatat(_STAT_VER, dirfd, stat_buf, flags) shall behave as fstatat(dirfd, stat_buf, flags) as specified by POSIX 1003.1-2008 (ISO/IEC 9945-2009).
__fxstatat() is not in the source standard; it is only in the binary standard.
Note: The fstatat() function is not in the binary standard; it is only in the source standard.
