SYNOPSIS
cc [ flag... ] file... -lform-lcurses [ library... ]
#include <form.h>
int set_field_buffer(FIELD *field, int buf, char *value);
char *field_buffer(FIELD *field, int buf);
int set_field_status(FIELD *field, int status);
int field_status(FIELD *field);
int set_max_field(FIELD *field, int max);
DESCRIPTIONset_field_buffer() sets buffer buf of field to value. Buffer 0 stores
the displayed contents of the field. Buffers other than 0 are applica‐
tion specific and not used by the forms library routines. field_buf‐
fer() returns the value of field buffer buf.
Every field has an associated status flag that is set whenever the con‐
tents 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 VALUESfield_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 Thefunction returned successfully.
