int audit(caddr_t record, int length);
The audit() function is used to write a record to the sys-
tem audit log. The data pointed to by record is written to
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
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:
The record argument points outside the process's allo-
cated address space.
The record header token ID is invalid or the length is
either less than the header token size or greater than
EPERM The process's effective user ID is not superuser.
Only the superuser can successfully execute this call.
