AUDIT(2) MidnightBSD System Calls Manual AUDIT(2)


audit — commit BSM audit record to audit log


#include <bsm/audit.h>


audit(const char *record, u_int length);


The audit() system call submits a completed BSM audit record to the system audit log.

The record argument is a pointer to the specific event to be recorded and length is the size in bytes of the data to be written.


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.


The audit() system call will fail and the data never written if:


The record argument is beyond the allocated address space of the process.


The token ID is invalid or length is larger than MAXAUDITDATA.


The process does not have sufficient permission to complete the operation.

The OpenBSM implementation was created by McAfee Research, the security division of McAfee Inc., under contract to Apple Computer Inc. in 2004. It was subsequently adopted by the TrustedBSD Project as the foundation for the OpenBSM distribution.


This software was created by McAfee Research, the security research division of McAfee, Inc., under contract to Apple Computer Inc. Additional authors include Wayne Salamon, Robert Watson, and SPARTA Inc.

The Basic Security Module (BSM) interface to audit records and audit event stream format were defined by Sun Microsystems.

The FreeBSD kernel does not fully validate that the argument passed is syntactically valid BSM. Submitting invalid audit records may corrupt the audit log.
