getuid

Intro

getuid - Retrieve user identity

Description

This event retrieves the user identity of the calling process. This is usually the real user ID of the calling process, but may be changed to the effective user ID or saved user ID depending on the implementation of the calling process.

The getuid event is useful for authentication of process and user identities in systems which require privilege separation. However, there are some potential drawbacks: it may not be possible to differentiate processes across userid boundaries, or between related userids in certain implementations.
