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

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);

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 */

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

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

EPERM

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