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.
