Routine Description:
 | 
						|
 | 
						|
  VSPrint function to process format and place the results in Buffer. Since a
 | 
						|
  VA_LIST is used this rountine allows the nesting of Vararg routines. Thus
 | 
						|
  this is the main print working routine
 | 
						|
 | 
						|
Arguments:
 | 
						|
 | 
						|
  StartOfBuffer - Unicode buffer to print the results of the parsing of Format into.
 | 
						|
 | 
						|
  BufferSize    - Maximum number of characters to put into buffer. Zero means
 | 
						|
                  no limit.
 | 
						|
 | 
						|
  FormatString  - Unicode format string see file header for more details.
 | 
						|
 | 
						|
  Marker        - Vararg list consumed by processing Format.
 | 
						|
 | 
						|
Returns:
 | 
						|
 | 
						|
  Number of characters printed.
