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

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.
|

|

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.
