+# NAME
+
+curl_multi_notify_enable - enable a notification type
+
+# SYNOPSIS
+
+~~~c
+#include <curl/curl.h>
+CURLMcode curl_multi_notify_enable(CURLM *multi_handle,
+                                   unsigned int notification);
+~~~
+
+# DESCRIPTION
+
+Enables collecting the given notification type in the multi handle. A
+callback function installed via CURLMOPT_NOTIFYFUNCTION(3) is called
+when this notification happens.
+
+Only when a notification callback is installed *and* a notification
+is enabled are these collected and dispatched to the callback.
+
+Several notification types can be enabled at the same time. Enabling
+an already enabled notification is not an error.
+
+A notification can be disabled again via curl_multi_notify_disable(3).

+
+# EXAMPLE
+
+~~~c
+int main(void)
+{
+  int rc;
+  CURLM *multi = curl_multi_init();
+
+  rc = curl_multi_notify_enable(multi, CURLMNOTIFY_INFO_READ);
+}
+~~~
+
+# %AVAILABILITY%
+
+# RETURN VALUE
+
+This function returns a CURLMcode indicating success or error.
+
+CURLM_OK (0) means everything was OK, non-zero means an error occurred, see
+libcurl-errors(3).
+
+The return code is for the whole multi stack. Problems still might have
+occurred on individual transfers even when one of these functions return OK.
