form_field_userptr(3)			    form_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-specific  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(3), 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 supported on Version 7 or BSD versions.

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

AUTHORS
       Juergen	Pfeifer.   Manual  pages  and  adaptation for new
       curses by Eric S. Raymond.
