GETAUDIT(2) System Calls GETAUDIT(2)

NAME

getaudit, setaudit, getaudit_addr, setaudit_addr - get or set process
audit information

SYNOPSIS

cc [ flag ... ] file ... -lbsm -lsocket -lnsl [ library ... ]
#include <sys/param.h>
#include <bsm/libbsm.h>

int getaudit(struct auditinfo *info);


int setaudit(struct auditinfo *info);


int getaudit_addr(struct auditinfo_addr *info, int length);


int setaudit_addr(struct auditinfo_addr *info, int length);

DESCRIPTION

The getaudit() function gets the audit ID, the preselection mask, the
terminal ID and the audit session ID for the current process.


The getaudit() function can fail and return an E2BIG errno if the address
field in the terminal ID is larger than 32 bits. In this case,
getaudit_addr() should be used.


The setaudit() function sets the audit ID, the preselection mask, the
terminal ID and the audit session ID for the current process.


The getaudit_addr() function returns a variable length auditinfo_addr
structure that contains the audit ID, the preselection mask, the terminal
ID, and the audit session ID for the current process. The terminal ID
contains a size field that indicates the size of the network address.


The setaudit_addr() function sets the audit ID, the preselection mask,
the terminal ID, and the audit session ID for the current process. The
values are taken from the variable length structure auditinfo_addr. The
terminal ID contains a size field that indicates the size of the network
address.


The auditinfo structure is used to pass the process audit information and
contains the following members:

au_id_t ai_auid; /* audit user ID */
au_mask_t ai_mask; /* preselection mask */
au_tid_t ai_termid; /* terminal ID */
au_asid_t ai_asid; /* audit session ID */


The auditinfo_addr structure is used to pass the process audit
information and contains the following members:

au_id_t ai_auid; /* audit user ID */
au_mask_t ai_mask; /* preselection mask */
au_tid_addr_t ai_termid; /* terminal ID */
au_asid_t ai_asid; /* audit session ID */

RETURN VALUES

Upon successful completion, getaudit() and setaudit() return 0.
Otherwise, -1 is returned and errno is set to indicate the error.

ERRORS

The getaudit() and setaudit() functions will fail if:

EFAULT
The info parameter points outside the process's allocated
address space.


EPERM
The {PRIV_SYS_AUDIT} privilege is not asserted in the effective
set of the calling process.

USAGE

The calling process must have the {PRIV_SYS_AUDIT} privilege asserted in
its effective set.
