In Unix-like operating systems, the getuid system call returns the real user ID of the calling process. The getuidx64 system call is a 64-bit extension of this system call, designed to handle 64-bit user IDs. Typically, system calls related to user ID retrieval do not require elevated privileges, as they only provide information about the calling process.
When working with deep system tools, game modifications, or complex deployment packages on Windows, you may encounter a strict error message stating: . getuidx64 require administrator privileges exclusive
The word "exclusive" in the error often implies that the resource getuidx64 is trying to access cannot be shared. If another monitoring tool (like HWMonitor, CPU-Z, or a driver updater) is already polling that specific hardware address, the second request will fail unless it has the authority to override or "exclusively" lock that process.

The term getuidx64 is not documented in standard POSIX or Linux manuals. The standard system call is getuid() (or geteuid() ), which retrieves the real user ID of the calling process. The original Linux getuid() system call only supported . After Linux 2.4, 32-bit user IDs were supported via getuid32() and geteuid32() system calls. The GNU C library (glibc) wrapper functions getuid() and geteuid() transparently handle the variations across kernel versions.
