Following is a tiny wrapper program that I wrote to use libwww to simply retrieve files, and send them out stdout. I find that it works with the first http URL I put in, but if I put in a second one, it core dumps. Here is the program... #include "WWWLib.h" #include "stubs.h" /* Just a bunch of HText_* function stubs */ #define MAX_URL_LEN 1024 main(int argc, char *argv[]) { char url[MAX_URL_LEN]; HTRequest *request; /* Initialize the library */ HTLibInit(); WWW_TraceFlag = TRUE; /* Set up the static part of our request structure */ request = HTRequest_new(); request->output_format = WWW_SOURCE; request->output_stream = HTFWriter_new(stdout, TRUE); /* Loop until close of stdin, reading in URLs */ while (gets(url)) HTLoadAbsolute(url, request); HTLibTerminate(); } Is there anything obviously wrong with it? Here is the output, after I put in the second URL... http://www.cen.com/mw3/ Composing Authorization for www.cen.com:80/mw3/ HTAASetup_lookup: No template matched `mw3/' (so probably not protected) HTMIME: MIME content type is text/html, converting to */* StreamStack.
