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.

PORTABILITY
