SYNOPSIS

cc [ flag... ] file... -lform -lcurses [ library... ]
#include <form.h>


int set_field_buffer(FIELD *field, int buf, char *value);

int set_field_status(FIELD *field, int status);


int field_status(FIELD *field);


int set_max_field(FIELD *field, int max);

DESCRIPTION

set_field_buffer() sets buffer buf of field to value. Buffer 0
stores the displayed contents of the field. Buffers other than 0 are
application specific and not used by the forms library routines.
field_buffer() returns the value of field buffer buf.


Every field has an associated status flag that is set whenever the
contents of field buffer 0 changes. set_field_status() sets the
status flag of field to status. field_status() returns the status of
field.


set_max_field() sets a maximum growth on a dynamic field, or if max=0
turns off any maximum growth.

RETURN VALUES

field_buffer() returns NULL on error.


field_status() returns TRUE or FALSE.


set_field_buffer(), set_field_status(), and set_max_field() return
one of the following:

E_OK
The function returned successfully.
