Hm, I don't think so, at least not according to the documentation:
Function: xmlSaveUri
xmlChar * xmlSaveUri (xmlURIPtr uri)
Save the URI as an escaped string
uri: pointer to an xmlURI
Returns: a new string (to be deallocated by caller)
The code in libxml2 also seems to confirm this, although it's not entirely
straightforward:
xmlChar *
xmlSaveUri(xmlURIPtr uri) {
xmlChar *ret = NULL;
xmlChar *temp;
const char *p;
int len;
int max;
if (uri == NULL) return(NULL);
max = 80;
ret = (xmlChar *) xmlMallocAtomic((max + 1) * sizeof(xmlChar));
...
ret[len] = 0;
return(ret);
}
So something else might be going on. What version of libxml2
are you currently building against?
