NAME
     dup_field, free_field, link_field, new_field - form library

LIBRARY
     Curses Form Library (libform, -lform)

SYNOPSIS
     #include <form.h>

     FIELD *
     dup_field(FIELD *field, int frow, int fcol);

     int
     free_field(FIELD *field);

     FIELD *
     link_field(FIELD *field, int frow, int fcol);

     FIELD *
     new_field(int rows, int cols, int frow, int fcol, int nrows, int nbuf);

DESCRIPTION
     The dup_field() function duplicates the given field, including any
     buffers associated with the field and returns the pointer to the newly
     created field.  free_field() destroys the field and frees any allocated
     resources associated with the field.  The function link_field() copies
     the given field to a new field at the location frow and fcol but shares
     the buffers with the original field.  new_field() creates a new field of
     size rows by cols at location frow, fcol on the page, the argument nrows
     specified the number of off screen rows the field has and the nbuf
     parameter specifies the number of extra buffers attached to the field.
     There will always be one buffer associated with a field.

RETURN VALUES
     On error dup_field() and new_field() will return NULL.  The functions
     will one of the following error values:

     E_OK               The function was successful.
     E_BAD_ARGUMENT     A bad argument was passed to the function.
     E_CONNECTED        The field is connected to a form.
