form_field_new(3X)					    form_field_new(3X)

NAME
       form_field_new - create and destroy form fields

SYNOPSIS
       #include <form.h>
       FIELD *new_field(int height, int width,
			int toprow, int leftcol,
			int offscreen, int nbuffers);
       FIELD *dup_field(FIELD *field, int toprow, int leftcol);
       FIELD *link_field(FIELD *field, int toprow, int leftcol);
       int free_field(FIELD *field);

DESCRIPTION
       The  function  new_field	 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 dup_field 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 link_field acts like dup_field, but the new	 field	shares
       buffers with its parent.	 Attribute data is separate.

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

RETURN VALUE
       The function, new_field, dup_field, link_field return NULL on error.

       The function free_field returns one of the following:

       E_OK The routine succeeded.

       E_SYSTEM_ERROR
	    System error occurred (see errno).

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

SEE ALSO
       curses(3X), 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  sup‐
       ported on Version 7 or BSD versions.

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