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 func-
     tion 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(3).

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.
