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 including
            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 writeBlanksAttrib 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  vertically
            (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 vertically
            (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.
