formfieldnew(3X)                                          formfieldnew(3X)



NAME
       formfieldnew - create and destroy form fields

SYNOPSIS
       ##include <>
       FIELD *newfield(int height, int width,
                        int toprow, int leftcol,
                        int offscreen, int nbuffers);
       FIELD *dupfield(FIELD *field, int toprow, int leftcol);
       FIELD *linkfield(FIELD *field, int toprow, int leftcol);
       int freefield(FIELD *field);

DESCRIPTION
       The  function  newfield  allocates a new field and initializes it from
       the parameters given: height, width, row of upper-left  corner,  column
       of  upper-left corner, number off-screen rows, and number of additional
       working buffers.

       The function dupfield duplicates a field  at  a  new  location.   Most
       attributes  (including  current contents, size, validation type, buffer
       count, growth threshold,  justification,  foreground,  background,  pad
       character, options, and user pointer) are copied.  Field status and the
       field page bit are not copied.

       The function linkfield acts like dupfield, but the new  field  shares
       buffers with its parent.  Attribute data is separate.

       The function freefield de-allocates storage associated with a field.

RETURN VALUE
       The function, newfield, dupfield, linkfield return NUL on error.

       The function freefield returns one of the following:

       EOK The routine succeeded.

       ESYSTEMEROR
            System error occurred (see errno).

       EBADARGUMENT
            Routine detected an incorrect or out-of-range argument.

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.

       It  may  be  unwise  to  count  on  the  set  of  attributes  copied by
       dupfield(3X) being portable; the System V forms library documents  are
       not very explicit about what gets copied and what doesn't.
