NAME
     form_field_info - retrieve field characteristics

SYNOPSIS
     #include 
     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  attri-
     butes  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
     curses(3X) and related pages whose names begin  "form_"  for
     detailed descriptions of the entry points.

NOTES
     The header file  automatically includes  the  header
     file .

PORTABILITY
     These routines emulate the System  V  forms  library.   They
     were not supported 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.
