getCode

Note

This is a point-in-time snapshot of the API documentation from January 2026. Going forward, we will not be maintaining a public copy of these references, and recommend users to refer to the built-in signature helpers available in the Hack LSP instead for complete and up-to-date information.

warning

Deprecated: Use getErrno() instead.

Deprecated for clarity, and potential future ambiguity

final public function getCode(): HH\Lib\OS\Errno;

In the future, we may have exceptions with multiple 'codes', such as an errno and a getaddrinfo GAI constant.

Keeping logging rate at 0 so that generic code that works on any exception stays happy.

Returns

• HH\Lib\OS\Errno
