This function sends a message to the client preferring to use the stderr channel as long as it is available and switching to using syslog() if it isn't. Generally the stderr channell will be available in the startup process and in the beginning of the first startup in the supervisor/daemon processes. Later on the stderr fd will be closed and we have to fall back to using the system log.

console_release()

void console_release

(

void

)

Restore input/output/error. This function is idempotent, can be called any number of times without harm.
