Function kqueue [src]

Prototype

pub fn kqueue() KQueueError!i32

Possible Errors

ProcessFdQuotaExceeded

The per-process limit on the number of open file descriptors has been reached.

SystemFdQuotaExceeded

The system-wide limit on the total number of open files has been reached.

Unexpected UnexpectedError

The Operating System returned an undocumented error code.

This error is in theory not possible, but it would be better to handle this error than to invoke undefined behavior.

When this error code is observed, it usually means the Zig Standard Library needs a small patch to add the error code to the error set for the respective function.
