 .SH DESCRIPTION
 In the macro definitions,

 that must contain a field of type
-.Li SLIST_ENTRY ,

 The argument
-.Fa HEADNAME
+.IR HEADNAME
 is the name of a user defined structure that must be declared
 using the macro

-.Ss Singly-linked lists
+.BR SLIST_HEAD ().
+.PP
 A singly-linked list is headed by a structure defined by the

 This structure contains a single pointer to the first element
 on the list.

 New elements can be added to the list after an existing element or
 at the head of the list.
 An

 structure is declared as follows:
-.Bd -literal -offset indent

 where
-.Fa HEADNAME

 is the name of the structure to be defined, and
-.Fa TYPE

 is the type of the elements to be linked into the list.
 A pointer to the head of the list can later be declared as:

 evaluates to an initializer for the list

 evaluates to true if there are no elements in the list.

 traverses the list referenced by
