Am I misreading this?
* virSetErrorFunc:
* @userData: pointer to the user data provided in the handler callback
* @handler: the function to get called in case of error or NULL
*
* Set a library global error handling function, if @handler is NULL,
* it will reset to default printing on stderr. The error raised there
* are those for which no handler at the connection level could caught.
*/
Looks like setting handler to Null reset default printing on stderr?
But I am getting no output whether or not I set this.


I am attaching a hacked virt-login-shell.c which gives me no output.
