NAME

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

SYNOPSIS

#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);

MT-LEVEL

Unsafe

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.
