form_field_new(3) UNIX Programmer's Manual form_field_new(3)NAMEform_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, valida-
tion 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 ALSOcurses(3), form(3).
NOTES
The header file <form.h> automatically includes the header
file <curses.h>.

form_field_new(3) UNIX Programmer's Manual form_field_new(3)PORTABILITY
These routines emulate the System V forms library. They
were not supported on Version 7 or BSD versions.
It may be unwise to count on the set of attributes copied by
dup_field(3) being portable; the System V forms library
documents are not very explicit about what gets copied and
what doesn't.
