HI,
I am using the binaries built at zlatkovic.com. When I am calling xmlFree
after calling xmlNodeListGetString, the program is crashing with a really
weird unhandled exception
Unhandled exception at 0x026332a0 in dconnect.exe: 0xC000001E: An attempt
was made to execute an invalid lock sequence.
For structural reasons I am not linking the DLL into my application by
using LoadLibrary and GetProcAddress. I am pretty sure the problem is that
the xmlFree address is incorrect, or I am passing an invalid argument but
I cant see what it could be.
My code is shown below
xmlFreeFunc lpXMLFREE = NULL;
HMODULE hXML = NULL;
BOOL InitXML()
{
if (hXML)
return(TRUE);
hXML = LoadLibrary("libxml2.dll");
if (hXML == NULL)
return(FALSE);
if (!(lpXMLNEWDOC = (LPXMLNEWDOC) GetProcAddress (hXML,
"xmlNewDoc")))
return(FALSE);
if (!(lpXMLFREEDOC = (LPXMLFREEDOC) GetProcAddress (hXML,
"xmlFreeDoc")))
return(FALSE);
if (!(lpXMLNEWNODE = (LPXMLNEWNODE) GetProcAddress (hXML,
"xmlNewNode")))
return(FALSE);
if (!(lpXMLDOCSETROOTELEMENT = (LPXMLDOCSETROOTELEMENT)
GetProcAddress (hXML, "xmlDocSetRootElement")))
return(FALSE);
if (!(lpXMLDOCGETROOTELEMENT = (LPXMLDOCGETROOTELEMENT)
GetProcAddress (hXML, "xmlDocGetRootElement")))
return(FALSE);
if (!(lpXMLNEWNS = (LPXMLNEWNS) GetProcAddress (hXML, "xmlNewNs"
)))
return(FALSE);
if (!(lpXMLNEWCHILD = (LPXMLNEWCHILD) GetProcAddress (hXML,
"xmlNewChild")))
return(FALSE);
if (!(lpXMLNEWTEXTCHILD = (LPXMLNEWTEXTCHILD) GetProcAddress
(hXML, "xmlNewTextChild")))
return(FALSE);
if (!(lpXMLSAVEFORMATFILEENC = (LPXMLSAVEFORMATFILEENC)
GetProcAddress (hXML, "xmlSaveFormatFileEnc")))
return(FALSE);
if (!(lpXMLSAVEFORMATFILE = (LPXMLSAVEFORMATFILE) GetProcAddress
(hXML, "xmlSaveFormatFile")))
return(FALSE);
if (!(lpXMLPARSEFILE = (LPXMLPARSEFILE) GetProcAddress (hXML,
"xmlParseFile")))
return(FALSE);
if (!(lpXMLSTRCMP = (LPXMLSTRCMP) GetProcAddress (hXML,
"xmlStrcmp")))
return(FALSE);
if (!(lpXMLNODELISTGETSTRING =
(LPXMLNODELISTGETSTRING)GetProcAddress(hXML, "xmlNodeListGetString")))
return(FALSE);
if (!(lpXMLFREE = (xmlFreeFunc)GetProcAddress(hXML, "xmlFree")))
return(FALSE);
return(TRUE);
}
void msaxmlFree(void *v)
{
lpXMLFREE(v);
}
