Automatic status logging.
|
|
|
|
Use TStatus instead of DWORD:
|
|
|
|
DWORD dwStatus; -> TStatus Status;
|
|
dwStatus = ERROR_SUCCESS -> Status DBGNOCHK = ERROR_SUCCESS;
|
|
dwStatus = xxx; -> Status DBGCHK = xxx;
|
|
if( dwStatus ){ -> if( Status != 0 ){
|
|
|
|
Anytime Status is set, the DBGCHK macro must be added before
|
|
the '=.'
|
|
|
|
If the variable must be set to a failure value at compilte time
|
|
and logging is therefore not needed, then the DBGNOCHK macro
|
|
should be used.
|
|
|
|
There are different parameters to instantiation. Alternate
|
|
debug level can be specified, and also 3 "benign" errors that
|
|
can be ignored.

TStatus Status( DBG_ERROR, ERROR_ACCESS_DENIED, ERROR_FOO );

|
|
|
Declare a class Work derived from the mix-in MExecWork. When
|
|
work needs to be done on an instantiation of Work, it is queued
|
|
and immediately returned. A DWORD bitfield--4 high bits are
|
|
predefined--indicates the type of work needed.
|
|
|
|
This DWORD should be a bitfield, so if there are multiple
|
|
bJobAdd requests and all threads are busy, these DWORDs are
|
|
OR'd together.
|
|
|
|
That is,
|
|
|
|
bJobAdd( pJobUnit, 0x1 );
|
|
bJobAdd( pJobUnit, 0x2 );
|
|
bJobAdd( pJobUnit, 0x4 );
|
|
bJobAdd( pJobUnit, 0x8 );
|
|
|
|
We will call svExecute with 0xf.
|
|
|
|
Two threads will never operate on one job simultaneously. This
|
|
is guarenteed by this library.
|
|
|
|
The worker routine is defined by the virtual function stExecute().
