NAME

       form_field_new, new_field, dup_field, link_field, free_field - create and destroy forms fields

SYNOPSIS

       cc [ flag... ] file... -lform  -lcurses	[ library... ]
       #include <form.h>

       FIELD *new_field(int r, int c, int frow, int fcol, int nrow, int ncol);

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

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

       int free_field(FIELD *field);

DESCRIPTION

       new_field()  creates  a new field with r rows and c columns, starting at frow, fcol, in the subwindow of a form. nrow is the number of off-
       screen rows and nbuf is the number of additional working buffers. This routine returns a pointer to the new field.

       dup_field() duplicates field at the specified location. All field attributes are duplicated, including the current contents  of	the  field
       buffers.

       link_field()  also duplicates field at the specified location. However, unlike dup_field(), the new field shares the field buffers with the
       original field. After creation, the attributes of the new field can be changed without affecting the original field.

       free_field() frees the storage allocated for field.

RETURN VALUES

       Routines that return pointers return NULL on error. free_field() returns one of the following:

       E_OK		 Thefunction returned successfully.

       E_CONNECTED	 The field is already connected to a form.

       E_SYSTEM_ERROR	 System error.

       E_BAD_ARGUMENT	 An argument is incorrect.
