.SH DESCRIPTION
A device ID consists of two parts:
These macros can be useful to, for example,
decompose the device IDs in the structure returned by
.BR stat (2).

+.SH CONFORMING TO
The
-.BR makedev ()
-.BR major ()
+.BR makedev (),
+.BR major (),
and
.BR minor ()
functions are not specified in POSIX.1,
These interfaces are defined as macros.
Since glibc 2.3.3,
they have been aliases for three GNU-specific functions:
-.BR gnu_dev_makedev (3),
-.BR gnu_dev_major (3),
+.BR gnu_dev_makedev (),
+.BR gnu_dev_major (),
and
-.BR gnu_dev_minor (3).
+.BR gnu_dev_minor ().
The latter names are exported, but the traditional names are more portable.
