The __fxstatat64() function shall implement the fstatat64() function. The behavior of __fxstatat64() 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.
__fxstatat64(_STAT_VER, dirfd, stat_buf, flags) shall behave as fstatat64(dirfd, stat_buf, flags) as specified by this specification.
__fxstatat64() is not in the source standard; it is only in the binary standard.
Note: The fstatat64() function is not in the binary standard; it is only in the source standard.
