  .Sh DESCRIPTION
  The mandoc HTML formatter is not a formal library.
  However, as it is compiled into more than one program, in particular

  functions.
  .Pp
+ The function
+ .Fn html_make_id
+ takes a node containing one or more text children
+ and returns a newly allocated string containing the concatenation
+ of the child strings, with blanks replaced by underscores.
+ If the node
+ .Fa n
+ contains any non-text child node,
+ .Fn html_make_id
+ returns
+ .Dv NULL
+ instead.
+ The caller is responsible for freeing the returned string.
+ .Pp
+ The function
+ .Fn html_strlen
+ counts the number of characters in
+ .Fa cp .
+ It is used as a crude estimate of the width needed to display a string.
