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

based on a Null-terminated 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.

@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.

@return Number of characters printed not including the Null-terminator.
