curl_multi_notify_disable(3) Introduction to Library Functions
curl_multi_notify_disable - disable a notification type
#include <curl/curl.h>
CURLMcode curl_multi_notify_disable(CURLM *multi_handle,
unsigned int notification);
Disables collecting the given notification type in the multi handle.
A callback function installed via CURLMOPT_NOTIFYFUNCTION(3) is no
longer 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. Disabling
an already disabled notification is not an error.
A notification can be enabled again via curl_multi_notify_enable(3).
This functionality affects all supported protocols
int main(void)
{
int rc;
CURLM *multi = curl_multi_init();
rc = curl_multi_notify_disable(multi, CURLMNOTIFY_INFO_READ);
}
Added in curl 8.17.0
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.
