  56 <H2>SYNOPSIS</H2><PRE>
  57        <STRONG>#include</STRONG> <STRONG>&lt;form.h&gt;</STRONG>
  58        int set_form_fields(FORM *form, FIELD **fields);

  65 <H2>DESCRIPTION</H2><PRE>
  66        The function <STRONG>set_form_fields</STRONG>  changes  the  field  pointer
  67        array  of the given <EM>form</EM>.  The array must be terminated by
  68        a <STRONG>NULL</STRONG>.
  69
  70        The function <STRONG>form_fields</STRONG> returns the field  array  of  the
  71        given form.
  72
  73        The  function  <STRONG>field_count</STRONG>  returns the count of fields in
  74        <EM>form</EM>.
  75
  76        The function <STRONG>move_field</STRONG> moves the given field (which  must
  77        be disconnected) to a specified location on the screen.
  78
  79
  80 </PRE>
  81 <H2>RETURN VALUES</H2><PRE>
  82        The  function  <STRONG>form_fields</STRONG> returns a pointer (which may be
  83        <STRONG>NULL</STRONG>).  It does not set errno.
  84
  85        The function <STRONG>field_count</STRONG> returns <STRONG>ERR</STRONG> if the <EM>form</EM> parameter
  86        is <STRONG>NULL</STRONG>.
  87
  88        The functions <STRONG>set_form_fields</STRONG> and <STRONG>move_field</STRONG> return one of
  89        the following codes on error:
  90
  91        <STRONG>E_OK</STRONG> The routine succeeded.
  92
  93        <STRONG>E_BAD_ARGUMENT</STRONG>
  94             Routine detected an incorrect or  out-of-range  argu-
  95             ment.
  96
  97        <STRONG>E_CONNECTED</STRONG>
  98             The field is already connected to a form.
  99
 100        <STRONG>E_POSTED</STRONG>
 101             The form is already posted.
 102
 103        <STRONG>E_SYSTEM_ERROR</STRONG>
 104             System error occurred (see <STRONG>errno</STRONG>).

 113 <H2>NOTES</H2><PRE>

 119 <H2>PORTABILITY</H2><PRE>
 120        These routines emulate the System V forms  library.   They
 121        were not supported on Version 7 or BSD versions.
 122
 123        The   SVr4   forms  library  documentation  specifies  the
 124        <STRONG>field_count</STRONG> error value as -1 (which is the value of <STRONG>ERR</STRONG>).
