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
The function returned successfully.
 
 
E_CONNECTED
The field is already connected to a form.
 
 
E_SYSTEM_ERROR
System error.
 
 
E_BAD_ARGUMENT
An argument is incorrect.
