Function setuid [src]

Prototype

pub fn setuid(uid: uid_t) SetIdError!void

Parameters

uid: uid_t

Possible Errors

InvalidUserId SetEidError

PermissionDenied SetEidError

ResourceLimitReached

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.
