form_field_info(3)			       form_field_info(3)

NAME
       form_field_info - retrieve field characteristics

SYNOPSIS
       #include <form.h>
       int field_info(const FIELD *field, int *rows, int *cols,
		     int *frow, int *fcol, int *nrow, int *nbuf);
       int dynamic_field_info(const FIELD *field, int *rows,  int
       *cols, *max);

DESCRIPTION
       The  function  field_info  returns  the	sizes  and  other
       attributes passed in to the field at  its  creation  time.
       The  attributes are: height, width, row of upper-left cor-
       ner, column of upper-left corner, number off-screen  rows,
       and number of working buffers.

       The function dynamic_field_info returns the actual size of
       the field, and its maximum possible size.   If  the  field
       has  no	size  limit,  the location addressed by the third
       argument will be set to 0.  (A field can be  made  dynamic
       by turning off the O_STATIC).

RETURN VALUE
       These routines return one of the following:

       E_OK The routine succeeded.

       E_SYSTEM_ERROR
	    System error occurred (see errno).

       E_BAD_ARGUMENT
	    Routine  detected  an incorrect or out-of-range argu-
	    ment.

SEE ALSO
       curses(3) and 3X	 pages	whose  names  begin  "form_"  for
       detailed descriptions of the entry points.

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

PORTABILITY
       These routines emulate the System V forms  library.   They
       were not supported on Version 7 or BSD versions.
