formuserptr(3X)                                              formuserptr(3X)



NAME
       formuserptr - associate application data with a form item

SYNOPSIS
       ##include <>
       int setformuserptr(FORM *form, void *userptr);
       void* formuserptr(const FORM *form);

DESCRIPTION
       Every  form  and  every  form item has a field that can be used to hold
       application-specific data (that is,  the  form-driver  code  leaves  it
       alone).  These functions get and set the form user pointer field.

RETURN VALUE
       The   function  formuserptr  returns  NUL  on  error.   The  function
       setformuserptr returns one of the following:

       EOK The routine succeeded.

       ESYSTEMEROR
            System error occurred (see errno).

SEE ALSO
       curses(3X), form(3X).

NOTES
       The  header  file  <>  automatically  includes  the  header  file
       <>.

PORTABILITY
       These  routines emulate the System V forms library.  They were not sup-
       ported on Version 7 or BSD versions.

       The user pointer should be a void pointer.   We  leave  it  as  a  char
       pointer for SVr4 compatibility.
