krb5_set_trace_callback - Specify a callback function for trace events.¶
- krb5_error_code krb5_set_trace_callback(krb5_context context, krb5_trace_callback fn, void * cb_data)¶
[in] context - Library context
[in] fn - Callback function
[in] cb_data - Callback data
Specify a callback for trace events occurring in krb5 operations performed within context . fn will be invoked with context as the first argument, cb_data as the last argument, and a pointer to a krb5_trace_info as the second argument. If the trace callback is reset via this function or context is destroyed, fn will be invoked with a NULL second argument so it can clean up cb_data . Supply a NULL value for fn to disable trace callbacks within context .
This function overrides the information passed through the KRB5_TRACE environment variable.
