There is no harm to add a manual page for the GNU typeof()-construct, given 

that it has already crawled into the source tree.

.Dt TYPEOF 3
.Os
.Sh NAME
.Nm typeof
.Nd GNU extension for type of an expression
.Sh SYNOPSIS
.Ft type
.Fn typeof "expression"
.Sh DESCRIPTION
The
.Fn typeof
construct can be used to obtain the type of an expression.
The syntax is comparable to that of
.Fn sizeof ,
but semantically
.Fn typeof
operates like a type name defined with
.Em typedef .
.Sh EXAMPLES
The following is a typical example of a type-generic macro:
.Bd -literal -offset indent
#define MAX(a, b) ({ \\
typeof(a) _a = (a); \\
typeof(b) _b = (b); \\
_a > _b ? _a : _b; \\
})
.Ed
.Sh SEE ALSO
.Xr gcc 1 ,
.Xr attribute 3 ,
.Xr offsetof 3
.Sh CAVEATS
The
.Fn typeof
construct is a non-standard, compiler-specific extension.

Most of the UNIX-like operating systems use GNU C as a system compiler,
but the various extensions of GNU C, such as
.Xr attribute 3 ,
.Xr attribute 3

.Xr typeof 3 ,
should not be considered standard features.
