NAME
     formfieldbuffer:  setfieldbuffer, fieldbuffer,
     setfieldstatus, fieldstatus, setmaxfield - set and get
     forms field attributes

SYNOPSIS
     #include <form.h>

     int setfieldbuffer(FIELD *field, int buf, char *value);
     char *fieldbuffer(FIELD *field, int buf);

     int setfieldstatus(FIELD *field, int status);
     int fieldstatus(FIELD *field);
     int setmaxfield(FIELD *field, int max);

DESCRIPTION
     setfieldbuffer 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.   fieldbuffer 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.
     setfieldstatus sets the status flag of  field  to  status.
     fieldstatus returns the status of field.

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

RETURN VALUE
     fieldbuffer returns NULL on  error.   fieldstatus  returns
     TRUE   or  FALSE.   setfieldbuffer,  setfieldstatus  and
     setmaxfield 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>.
