getauid(2)							   System Calls 							getauid(2)

NAME
getauid, setauid - get or set user audit identity SYNOPSIS
cc [ flag ... ] file ... -lbsm -lsocket -lnsl [ library ... ] #include <sys/param.h> #include <bsm/libbsm.h> int getauid(au_id_t *auid); int setauid(au_id_t *auid); DESCRIPTION
The getauid() function returns the audit user ID for the current process. This value is initially set at login time and inherited by all child processes. This value does not change when the real/effective user IDs change, so it can be used to identify the logged-in user even when running a setuid program. The audit user ID governs audit decisions for a process. The setauid() function sets the audit user ID for the current process. RETURN VALUES
Upon successful completion, the getauid() function returns the audit user ID of the current process on success. Otherwise, it returns -1 and sets errno to indicate the error. Upon successful completion the setauid() function returns 0. Otherwise, -1 is returned and errno is set to indicate the error. ERRORS
The getauid() and setauid() functions will fail if: EFAULT The auid argument points to an invalid address. EPERM The {PRIV_SYS_AUDIT} privilege is not asserted in the effective set of the calling process. The getauid() function will fail if: EPERM The {PRIV_PROC_AUDIT} privilege is not asserted in the effective set of the calling process. USAGE
Only a process with appropriate privileges can successfully execute these calls. SEE ALSO

The functionality described on this manual page is available only if the Solaris Auditing has been enabled. See bsmconv(1M) for more information. These functions have been superseded by getaudit(2) and setaudit(). SunOS 5.11 16 Apr 2008 getauid(2)

SETAUID(2)						      BSD System Calls Manual							SETAUID(2)

NAME
setauid -- set audit indentifier SYNOPSIS
#include <bsm/audit.h> int setauid(au_id_t *auid); DESCRIPTION
The setauid() system call sets the active audit identifier for the current process from the au_id_t pointed to by auid. The value of AU_DEFAUDITID (-1) should not be used for auid. This system call requires an appropriate privilege to complete. Once the audit identifier is set to some other value than AU_DEAUDITID (-1) then it is immutable. This system call may be used to set the audit identifier after initially setting up the audit session with the setaudit(2), or setaudit_addr(2) system call. RETURN VALUES
Upon successful completion, the value 0 is returned; otherwise the value -1 is returned and the global variable errno is set to indicate the error. ERRORS
The setauid() function will fail if: [EFAULT] A failure occurred while data transferred to the kernel failed. [EINVAL] An invalid value for auid was used. auid can be any value of type au_id_t except AU_DEFAUDITID. [EPERM] The process does not have sufficient permission to complete the operation. SEE ALSO
