DESCRIPTION

       These functions perform useful drawing and attribute operations.


AVAILABLE FUNCTIONS

       boxWindow
            draw  a box with on the window win.  Like attrbox, this function
            ORs attr with each character as it draws the box.

       attrbox
            draw a box with on the window win letting the caller define each
            element of the box.

            The  parameters  tlc,  trc,  blc, brc are used for the top-left,
            top-right, bottom-left and  bottom-right  corners  respectively.
            The  parameters  horz  and  vert are used for the horizontal and
            vertical sides of the box.  Any of these parameters may be zero.
            In  that  case,  the function skips the corresponding element of
            the box.

            The function ORs attr with each character as it draws the box.

       drawObjBox
            Draw a box around  the  given  window  win  using  the  object's
            defined line-drawing characters.

       drawLine
            draw a line on the given window.

            The parameters starty, startx are the starting coordinates.  The
            parameters endy, endx are the ending coordinates.  The  function
            writes the data in line to each coordinate in that range includ-
            ing the start/end coordinates.

            The function handles lines other than  vertical  or  horizontal,
            but  normally  it  is  used  for  that,  e.g.,  with line set to
            ACS_HLINE or ACS_VLINE.

       drawShadow
            draw a shadow on the right and bottom edges of a window.

       writeBlanks
            write a string of blanks, using writeChar.  The  parameters  are
            passed  to  writeChar  as  is.  There is no corresponding write-
            BlanksAttrib function.

       writeChar
            writes out a  char *  string  without  adding  attributes.   The
            parameters are passed to writeCharAttrib as is.

       writeCharAttrib
            writes out a char * string with the given attributes added.  The
            string is written to the given window, using its relative screen
            coordinates ypos and xpos.

            Compare with writeChtypeAttrib, which writes a chtype * string.

            The  function  ORs  the  attribute  attr with each item from the
            string.  For instance, it may be A_BOLD.   The  align  parameter
            controls whether it is written horizontally (HORIZONTAL) or ver-
            tically (VERTICAL).

            Finally, only a subset of the string is written.   The  function
            starts  with  the  data  from the start item of string, and ends
            before the end item.  If start is greater than, or equal to end,
            no data is written.

       writeChtype
            writes  out  a  chtype *  string without adding attributes.  The
            parameters are passed to writeChtypeAttrib as is.

       writeChtypeAttrib
            writes out a chtype * string with the  given  attributes  added.
            The  string  is  written to the given window, using its relative
            screen coordinates ypos and xpos.  You would normally  construct
            the string from a char * string using char2Chtype (3).

            The  function  ORs  the  attribute  attr with each item from the
            string.  For instance, it may be A_BOLD.   The  align  parameter
            controls whether it is written horizontally (HORIZONTAL) or ver-
            tically (VERTICAL).

            Finally, only a subset of the string is written.   The  function
            starts  with  the  data  from the start item of string, and ends
            before the end item.  If start is greater than, or equal to end,
            no data is written.
