form_field_new(S)

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

Syntax

cc ... -lform -lcurses

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

link_field(S) 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(S) 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.

Warning

The header file form.h automatically includes the header files eti.h and curses.h.
