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