Parameter

Description

The panic kernel service is called when a catastrophic error occurs and the system can no longer continue to operate. The panic service performs these two actions:

Writes the character string pointed to by the s parameter to the error log.
Performs a system dump.

The system halts after the dump. You should wait for the dump to complete, reboot the system, and then save and analyze the dump.

Execution Environment

The panic kernel service can be called from either the process or interrupt environment.

Return Values

The panic kernel service has no return values.
