NAME
     form_field_buffer:  set_field_buffer, field_buffer,
     set_field_status, field_status, set_max_field - set and get
     forms field attributes

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  when-
     ever    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:
     E_OK           - The function returned successfully.
     E_SYSTEM_ERROR - System error.
     E_BAD_ARGUMENT - An argument is incorrect.

NOTES
     The header file <form.h> automatically includes  the  header
     files <eti.h> and <curses.h>.
