Description Marc-Andre Lureau 2008-08-31 19:34:01 UTC 
This function could very well server other purposes than in GStreamer only, at least in my case ;)

Adapted from GStreamer gsturi.c

static void
g_uri_is_valid (const gchar * uri)
{
  gchar *check = (gchar *) uri;

  g_assert (uri != NULL);

  if (g_ascii_isalpha (*check)) {
    check++;
    while (g_ascii_isalnum (*check) || *check == '+'
        || *check == '-' || *check == '.')
      check++;
  }

  return check == ':';
}
Comment 1 Marc-Andre Lureau 2008-08-31 19:38:33 UTC 
obviously missing some stuff now that I compile it:

gboolean
g_uri_is_valid (const gchar * uri)
{
  gchar *check = (gchar *) uri;

  g_assert (uri != NULL);

  if (g_ascii_isalpha (*check)) {
    check++;
    while (g_ascii_isalnum (*check) || *check == '+'
	   || *check == '-' || *check == '.')
      check++;
  }

  return *check == ':';
}

Comment 3 Alexander Larsson 2008-09-25 09:07:07 UTC 
This is a very weak validity check. For instance, it allows non-ascii after the colon, which I'm not sure is valid. However, validation is a very tricky thing in general, so we should imho do minimal absolutely correct validation, and then document exactly what we mean by a uri being "valid".
Comment 4 Marc-Andre Lureau 2015-03-26 15:32:58 UTC 
bug 489862 provides a much better g_uri_is_valid(), let's close as dup
