Hi All,
I have written a piece of code something like this and I am calling the function xrayhttpget after a fixed time interval repeatetively .But I have encountered a problem in this
Suppose I give a valid uri of some html document and as I said my program logic will continuosly loop and try to fetch this document in each iteration .Also I have specified the
time gap between the successive requests is 3 seconds then during the second iteration my program gives segmentaion fault and it occurs due to the HTHost_setEventTimeout(3000);
call in the code.Could anyone explain me why this could occur?
Thanks
Sandesh
PRIVATE int request_terminater (HTRequest * request, HTResponse * response,
void * param, int status)
{
/*Stop the event loop and quit*/
HTEventList_stopLoop ();
return HT_OK;
}
/* ------------------------------------------------------------------------- */
/* xrayhttpget will now accept the uri and length of the uri*/
int xrayhttpget ( char * argv ,int len, int completeURI)
{
App * app = NULL;
HTRequest * request = NULL;
HTAnchor * anchor = NULL;
/* Need our own trace and print functions */
HTPrint_setCallback(printer);
HTTrace_setCallback(tracer);
char * uri = HTParse(argv, NULL, PARSE_ALL);
if ((anchor = HTAnchor_findAddress(uri)) == NULL)
anchor = HTAnchor_findAddress(DEFAULT_HOME);
HT_FREE(uri);
#if 0
HTSetTraceMessageMask("sop");
#endif
/* Initiate libwww */
libwww_setup();
/* Create a new app obect */
app = App_new();
/* Add our own request terminate handler */
HTNet_addAfter(request_terminater, NULL, app, HT_ALL, HT_FILTER_LAST);
/*Set the timeout for request */
HTHost_setEventTimeout(3000);
