set_field_userptr(3)

NAME

       form_field_userptr - associate application data with a form field

SYNOPSIS

       #include <form.h>
       int set_field_userptr(FIELD *field, void*userptr);
       void *field_userptr(const FIELD *field);

DESCRIPTION

       Every  form field has a field that can be used to hold application-spe-
       cific data (that is, the form-driver  code  leaves  it  alone).	 These
       functions get and set that field.

RETURN VALUE

       The   function  field_userptr  returns  NULL  on  error.  The  function
       set_field_userptr returns one of the following:

       E_OK The routine succeeded.

       E_SYSTEM_ERROR
	    System error occurred (see errno).

SEE ALSO

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

NOTES

       The  header  file  <form.h>  automatically  includes  the  header  file
       <curses.h>.

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.
