panic¶
Panic handling framework.
A ‘panic’ is raised by the EOS SDK to signal a programming error on behalf of the SDK user. A regular ‘assert’ is used by the SDK to signal an Arista error which should be reported for correction.
Panics occur under a number of conditions, such as an invalid string format for an IP address when using ip_addr_t’s constructor to checks of incompatible type attributes during manager calls. The panic exception passed to the exception_handler_t callback describes the fault condition observed.
During a panic call, any panic handler set with exception_handler_is is called with the message, and then the panic message is also written to stderr and a SIGABRT raised. The SIGABRT will also cause a stack trace to be dumped.
