NAME

au_preselect - preselect an audit event
 

SYNOPSIS

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

int au_preselect(au_event_t event, au_mask_t *mask_p, int sorf, int flag);

DESCRIPTION

The au_preselect() function determines whether the audit event event is preselected against the binary preselection mask pointed to by mask_p (usually obtained by a call to getaudit(2)). The au_preselect() function looks up the classes associated with event in audit_event(4) and compares them with the classes in mask_p. If the classes associated with event match the classes in the specified portions of the binary preselection mask pointed to by mask_p, the event is said to be preselected.

The sorf argument indicates whether the comparison is made with the success portion, the failure portion, or both portions of the mask pointed to by mask_p.

The following are the valid values of sorf:

AU_PRS_SUCCESS

Compare the event class with the success portion of the preselection mask.

AU_PRS_FAILURE

Compare the event class with the failure portion of the preselection mask.

AU_PRS_BOTH

Compare the event class with both the success and failure portions of the preselection mask.

The flag argument tells au_preselect() how to read the audit_event(4) database. Upon initial invocation, au_preselect() reads the audit_event(4) database and allocates space in an internal cache for each entry with malloc(3C). In subsequent invocations, the value of flag determines where au_preselect() obtains audit event information. The following are the valid values of flag:

AU_PRS_REREAD

Get audit event information by searching the audit_event(4) database.

AU_PRS_USECACHE

Get audit event information from internal cache created upon the initial invocation. This option is much faster.

RETURN VALUES

Upon successful completion,au_preselect() returns 0 if event is not preselected or 1 if event is preselected. If au_preselect() could not allocate memory or could not find event in the audit_event(4) database, -1 is returned.

NOTES

The au_preselect() function is normally called prior to constructing and writing an audit record. If the event is not preselected, the overhead of constructing and writing the record can be saved.

The functionality described on this manual page is available only if the Solaris Auditing has been enabled. See bsmconv(1M) for more information.
