new_form, free_form - create and destroy forms

SYNOPSIS DESCRIPTION RETURN VALUE PORTABILITY AUTHORS SEE ALSO

#include <form.h>

FORM *new_form(FIELD **fields);
int free_form(FORM *form);

The function new_form creates a new form connected to a specified field pointer array (which must be NULL-terminated).

The function free_form disconnects form from its field array and frees the storage allocated for the form.

The function new_form returns NULL on error. It sets errno according to the function's success:

E_OK	The routine succeeded.
E_BAD_ARGUMENT
	Routine detected an incorrect or out-of-range argument.
E_CONNECTED
	The field is already connected to a form.
E_SYSTEM_ERROR
	System error occurred, e.g., malloc failure.
The function free_form returns one of the following:
E_OK	The routine succeeded.
E_BAD_ARGUMENT
	Routine detected an incorrect or out-of-range argument.
E_POSTED
	The form has already been posted.

These routines emulate the System V forms library. They were not supported on Version 7 or BSD versions.
