Example

This example shows forwarding debug information through a chain of routines.

void ReportFunction( int sum DBG_PASS )
{
    printf( "%s(%d):started this whole mess\n" DBG_RELAY );
}
   
void TrackingFunction( int a, int b DBG_PASS )
{
    ReportFunction( a+b, DBG_RELAY );
}
   
void CallTrack( void )
{
    TrackingFunction( 1, 2 DBG_SRC );
}

In this example, the debug information is passed to the logging system. This allows logging to blame the user application for allocations, releases, locks, etc...

void MyAlloc( int size DBG_PASS )
{
    _lprintf( DBG_RELAY )( ": alloc %d\n", size );
}
void g( void )
{
    lprintf( "Will Allocate %d\n", 32 );
    MyAlloc( 32 DBG_SRC );
}

This example uses the void argument macros

   
void SimpleFunction( DBG_VOIDPASS )
{
    // this function usually has (void) parameters.
}
   
void f( void )
{
    SimpleFunction( DBG_VOIDSRC );
}
