form_field_new(3ocurses)


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

Synopsis

cc [flag . . .] file -lform -locurses [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> value

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.

 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.

Notices

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