segfaults :(
only this works:
char buf[1024];
int n;
while ((n = evbuffer_remove(req->buffer_in, buf, sizeof(buf))) > 0) {
fwrite(buf, 1, n, stdout);
}
printf("\n");
or this:
int max_len = 1024
int len = evbuffer_get_length(req->buffer_in);
if (len == 0 || len >= max_len) {
return;
}
char buf[max_len];
evbuffer_remove(req->buffer_in, buf, len);
buf[len] = '\0';
printf("%s\n", buf);
