int audit(caddr_t record, int length);
The audit() function queues a record for writing to the system audit log.
The data pointed to by record is queued for the log after a minimal
consistency check, with the length parameter specifying the size of the
record in bytes. The data should be a well-formed audit record as described by
audit.log(4).
The kernel validates the record header token type and length, and
sets the time stamp value before writing the record to the audit log. The
kernel does not do any preselection for user-level generated events. If the
audit policy is set to include sequence or trailer tokens, the kernel will
append them to the record.
Upon successful completion, 0 is returned. Otherwise, −1 is
returned and errno is set to indicate the error.
The audit() function will fail if:
E2BIG
The record length is greater than the maximum allowed
record length.
EFAULT
The record argument points outside the process's
allocated address space.
EINVAL
The header token in the record is invalid.
ENOTSUP
Audit is not defined for this system.
EPERM
The {PRIV_PROC_AUDIT} privilege is not asserted in
the effective set of the calling process.
Only privileged processes can successfully execute this call.
