 arbitrary data structures in a machine-independent fashion.
 Data for remote procedure calls are transmitted using these
 routines.

 A filter primitive that translates between variable-length
 arrays
 and their corresponding external representations.
 The
 parameter
-.I arrp
+.Fa arrp
 is the address of the pointer to the array, while
-.I sizep
+.Fa sizep
 is the address of the element count of the array;
 this element count cannot exceed
-.IR maxsize .

 The parameter
-.I elsize
+.Fa elsize
 is the

 each of the array's elements, and
-.I elproc
+.Fa elproc
 is an

 A filter primitive that translates between a discriminated C
-.B union
+.Vt union
 and its corresponding external representation.
 It first
 translates the discriminant of the union located at
-.IR dscmp .
+.Fa dscmp .
 This discriminant is always an
-.BR enum_t .
+.Vt enum_t .
 Next the union located at
-.I unp
-is translated.  The parameter
-.I choices
+.Fa unp
+is translated.
+The parameter
+.Fa choices
 is a pointer to an array of
-.B xdr_discrim(\|)
+.Vt xdr_discrim
 structures.
 Each structure contains an ordered pair of
-.RI [ value , proc ].
+.Bq Va value , proc .
 If the union's discriminant is equal to the associated
-.IR value ,
+.Va value ,
 then the
-.I proc
-is called to translate the union.  The end of the
-.B xdr_discrim(\|)
+.Fn proc
+is called to translate the union.
+The end of the
+.Vt xdr_discrim
 structure array is denoted by a routine of value
-.SM NULL\s0.
+.Dv NULL .
 If the discriminant is not found in the
-.I choices
+.Fa choices
 array, then the
-.I defaultarm
+.Fn defaultarm
 procedure is called (if it is not
-.SM NULL\s0).
+.Dv NULL ) .
 Returns one if it succeeds, zero otherwise.

 A filter primitive that translates between fixed-length

+and their corresponding external representations.
+The
 parameter
-.I arrp
+.Fa arrp
 is the address of the pointer to the array, while
-.I size
-is the element count of the array.  The parameter
-.I elsize
+.Fa size
+is the element count of the array.
+The parameter
+.Fa elsize
 is the

 each of the array's elements, and

+.Fa elproc
 is an

 filter that translates between
 the array elements' C form, and their external
 representation.
 This routine returns one if it succeeds, zero otherwise.
