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.
