 /**
-  Worker function that produces a Null-terminated string in an output buffer

+  Produces a Null-terminated Unicode string in an output buffer based on
+  a Null-terminated Unicode format string and a VA_LIST argument list.
 
-  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.
+  This function is similar as vsnprintf_s defined in C11.
 
-  @param  Buffer      Character buffer to print the results of the parsing
-                      of Format into.
-  @param  BufferSize  Maximum number of characters to put into buffer.
-  @param  Flags       Intial flags value.
-                      Can only have FORMAT_UNICODE and OUTPUT_UNICODE set.
-  @param  Format      Null-terminated format string.
-  @param  Marker      Vararg list consumed by processing Format.
+  Produces a Null-terminated Unicode string in the output buffer specified by StartOfBuffer
+  and BufferSize.
+  The Unicode string is produced by parsing the format string specified by FormatString.
+  Arguments are pulled from the variable argument list specified by Marker based on the
+  contents of the format string.
+  The number of Unicode characters in the produced output buffer is returned not including
+  the Null-terminator.
 
-  @return Number of characters printed not including the Null-terminator.
+  If StartOfBuffer is not aligned on a 16-bit boundary, then ASSERT().
+  If FormatString is not aligned on a 16-bit boundary, then ASSERT().
