field_info(3FORM)                                            field_info(3FORM)

NAME
       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 option with field_opts_off.

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
       ncurses(3NCURSES)  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.
