Abstract:
|
|
|
|
Include file for in-memory DbgPrint function. Including this file
|
|
will change DbgPrints to a routine which puts the display text in a
|
|
circular buffer in memory. By default, the text is then sent to the
|
|
console via DbgPrint. By changing the value of the MemPrintFlags
|
|
flag, however, the text may be routed to a file instead, thereby
|
|
significantly speeding up the DbgPrint operation.
