DOMString::transcode()
Quick question:
Sometimes when I try to free pointer returned by DOMString::transcode()
I get an exception thrown from deep inside of "delete" operator:
DOMString dstr = elem.getAttribute("name");
char* ptr = dstr.transcode();
printf("%s", ptr);
delete[] ptr; //<<< boooom!
I suspect that this happens because the memory is allocated in one DLL and
is actually freed from another one.
Do you by any chance have a function in XML4C dll which could be used to
free allocated by the DLL resources? Something like that
void XML4C_free( char* ptr )
{
if ( ptr )
{
delete[] ptr;
ptr = NULL;
}
}
Thanks,

Re: DOMString::transcode()

Dean,
Is there a problem compiling and using xerces-c_1_2.dll which was built
using the
"Release Multi-threaded" compiler option instead of the "Release
Multi-threaded DLL"
option?
I used "Release Multi-threaded" and "Debug Multi-threaded" to build versions
of
xerces-c_1_2.dll to link with .exe and COM dll applications. This way I was
able to
delete anything allocated from DOMString::transcode(); from within the apps.
I do not understand the implications of using the non-dll version of the
multithreaded lib.
Any insight would be greatly appreciated.
Thanks,
- Tom

YOu have to build your own project with the same runtime as the parser. The
production DLLs are "Multi-threaded DLL". If you use anything else, you are
asking for trouble. If you want to do a debug build of your stuff, you still
have to use the non-debug runtime, unless you rebuild our stuff for debug
mode.
