NAME
form_field_buffer - field buffer control
SYNOPSIS
#include <form.h>
int set_field_buffer(FIELD *field, int buf, char *value);
char *field_buffer(FIELD *field, int buffer);
int set_field_status(FIELD *field, int status);
int field_status(FIELD *field);
int set_max_field(FIELD *field, int max);
DESCRIPTION
The function set_field_buffer sets the numbered buffer of the given field
to contain a given string. Buffer 0 is the displayed value of the field; other
numbered buffers may be allocated by applications through the nbuf
argument of (see field_new(3X)) but are not manipulated by the forms
library. The function field_buffer returns the foreground attribute.
The function set_field_status sets the associated status flag of
field; field_status gets the current value. The status flag
is set to a nonzero value whenever the field changes.
The function set_max_field sets the maximum size for a dynamic field.
An argument of 0 turns off any maximum size threshold for that field.
RETURN VALUE
The field_buffer function returns NULL on error.
The field_status function returns TRUE or FALSE.
The remaining routines return one of the following:
- E_OK
-
The routine succeeded.
- E_SYSTEM_ERROR
-
System error occurred (see errno).
- E_BAD_ARGUMENT
-
Routine detected an incorrect or out-of-range argument.

Version 7 or BSD versions.
