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 param-
	    eters 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, i.e., from indices start to end.

       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, i.e., from indices start to end.
