GETUID(2) Linux Programmer's Manual GETUID(2)
NAME
getuid, geteuid - get user identity
SYNOPSIS
#include <unistd.h>
#include <sys/types.h>
uid_t getuid(void);
uid_t geteuid(void);
DESCRIPTION
getuid() returns the real user ID of the calling process.
geteuid() returns the effective user ID of the calling process.
When a normal program is executed, the effective and real user ID of the process are set to the ID of the user executing the file. When a
set ID program is executed the real user ID is set to the calling user and the effective user ID corresponds to the set ID bit on the file
being executed.
ERRORS
These functions are always successful.
CONFORMING TO
POSIX.1-2001, 4.3BSD.
NOTES
History
In Unix V6 the getuid() call returned (euid << 8) + uid. Unix V7 introduced separate calls getuid() and geteuid().
SEE ALSO
getresuid(2), setreuid(2), setuid(2), credentials(7)
