form_requestname(3x) Library calls form_requestname(3x)
       form_request_by_name, form_request_name - handle printable form request
       names
       #include <form.h>
       const char *form_request_name(int request);
       int form_request_by_name(const char *name);
       The  function  form_request_name  returns  the printable name of a form
       request code.  The function form_request_by_name searches in the  name-
       table  for  a request with the given name and returns its request code.
       Otherwise E_NO_MATCH is returned.
       form_request_name  returns  NULL   on   error   and   sets   errno   to
       E_BAD_ARGUMENT.
       form_request_by_name  returns  E_NO_MATCH  on  error.   It does not set
       errno.
       These routines are specific to ncurses.  They  were  not  supported  on
       Version 7, BSD or System V implementations.  It is recommended that any
       code depending on them be conditioned using NCURSES_VERSION.
