For the XSFoundation project, I've coded an integrated debugger, that signals memory faults.
On Mac OS X or Unix-like system, I can use the backtrace() function, from execinfo.h to retrieve a function call stack, when necessary.
This way, when a fault occurs, the debugger can show you where the fault occurred.
As XSFoundation is a portable library, I had to do the same thing on Windows.
I first try using the StackWalk64 function, with no luck.
At last, I found a solution using the CaptureBackTrace function, from the MS API.
The output will be the following:
6: printStack - 0xD2430 5: wmain - 0xD28F0 4: __tmainCRTStartup - 0xE5010 3: wmainCRTStartup - 0xE4FF0 2: BaseThreadInitThunk - 0x75BE3665 1: RtlInitializeExceptionChain - 0x770F9D0F 0: RtlInitializeExceptionChain - 0x770F9D0F
Here's the actual code to achieve this:
void printStack( void );
void printStack( void )
{
unsigned int i;
void * stack[ 100 ];
unsigned short frames;
SYMBOL_INFO * symbol;
HANDLE process;
process = GetCurrentProcess();
SymInitialize( process, NULL, TRUE );
frames = CaptureStackBackTrace( 0, 100, stack, NULL );
symbol = ( SYMBOL_INFO * )calloc( sizeof( SYMBOL_INFO ) + 256 * sizeof( char ), 1 );
symbol->MaxNameLen = 255;
symbol->SizeOfStruct = sizeof( SYMBOL_INFO );
for( i = 0; i < frames; i++ )
{
SymFromAddr( process, ( DWORD64 )( stack[ i ] ), 0, symbol );
printf( "%i: %s - 0x%0X\n", frames - i - 1, symbol->Name, symbol->Address );
}
free( symbol );
}
