SYNOPSIS

#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);

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 VALUE

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:
