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, int
       *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 corner, 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 argument.

SEE ALSO
       curses(3X) and related 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 sup-
       ported on Version 7 or BSD versions.

       A  null	(zero  pointer)	 is accepted for any of the return values, to
       ignore that value.  Not all implementations allow this, e.g.,  Solaris
       2.7 does not.
