NAMEgetuid, geteuid − get user identity
LIBRARYStandard C library (libc, −lc)
SYNOPSIS#include <unistd.h>uid_t getuid(void);
uid_t geteuid(void);
DESCRIPTIONgetuid() returns the real user ID of the calling process. geteuid() returns the effective user ID of the calling process.
ERRORSThese functions are always successful and never modify errno.
STANDARDSPOSIX.1-2001, POSIX.1-2008, 4.3BSD.
NOTES
HistoryIn UNIX V6 the getuid() call returned (euid << 8) + uid. UNIX V7 introduced separate calls getuid() and geteuid(). The original Linux getuid() and geteuid() system calls supported only 16-bit user IDs. Subsequently, Linux 2.4 added getuid32() and geteuid32(), supporting 32-bit IDs. The glibc getuid() and geteuid() wrapper functions transparently deal with the variations across kernel versions. On Alpha, instead of a pair of getuid() and geteuid() system calls, a single getxuid() system call is provided, which returns a pair of real and effective UIDs. The glibc getuid() and geteuid() wrapper functions transparently deal with this. See syscall(2) for details regarding register mapping.
