The __xmknod() function shall implement the mknod() interface. The behavior of __xmknod() for values of ver other than _MKNOD_VER is undefined. See Data Definitions in the architecture specific part of this specification for the correct value of _MKNOD_VER.
__xmknod(_MKNOD_VER, path, mode, dev) shall behave as mknod(path, mode, dev) as specified by ISO POSIX (2003).
The __xmknod() function is not in the source standard; it is only in the binary standard.
Note: The mknod() function is not in the binary standard; it is only in the source standard.
