audctl(2) audctl(2)
NAME
audctl - start or halt the auditing system and set or get audit files
SYNOPSIS
#include <sys/audit.h>
int audctl(int cmd, char *cpath, char *npath, mode_t mode);
DESCRIPTION
audctl() sets or gets the auditing system "current" and "next" audit files, and starts or halts the audit-
ing system. This call is restricted to superusers. cpath and npath hold the absolute path names of the
"current" and "next" files. mode specifies the audit file’s permission bits. cmd is one of the following
specifications:
AUD_ON The caller issues the AUD_ON command with the required "current" and
"next" files to turn on the auditing system. If the auditing system is currently
off, it is turned on; the file specified by the cpath parameter is used as the
"current" audit file, and the file specified by the npath parameter is used as
the "next" audit file. If the audit files do not already exist, they are created
with the mode specified. The auditing system then begins writing to the
specified "current" file. An empty string or
NULL npath can be specified if the
caller wants to designate that no "next" file be available to the auditing sys-
tem. If the auditing system is already on, no action is performed;
-1 is
returned and errno is set to EBUSY.
AUD_GET The caller issues the AUD_GET command to retrieve the names of the
"current" and "next" audit files. If the auditing system is on, the names of the
"current" and "next" audit files are returned via the cpath and npath parame-
ters (which must point to character buffers of sufficient size to hold the file
names). mode is ignored. If the auditing system is on and there is no avail-
able "next" file, the "current" audit file name is returned via the cpath parame-
ter, npath is set to an empty string;
-1 is returned, and errno is set to
ENOENT. If the auditing system is off, no action is performed;
-1 is returned
and
errno is set to EALREADY.
AUD_SET The caller issues the AUD_SET command to change both the "current" and
"next" files. If the audit system is on, the file specified by cpath is used as the
"current" audit file, and the file specified by npath is used as the "next" audit
file. If the audit files do not already exist, they are created with the specified
mode. The auditing system begins writing to the specified "current" file.
Either an empty string or
NULL npath can be specified if the caller wants to
designate that no "next" file be available to the auditing system. If the audit-
ing system is off, no action is performed; -1 is returned and errno is set to
EALREADY.
AUD_SETCURR The caller issues the AUD_SETCURR command to change only the "current"
audit file. If the audit system is on, the file specified by cpath is used as the
"current" audit file. If the specified "current" audit file does not exist, it is
created with the specified mode. npath is ignored. The auditing system
begins writing to the specified "current" file. If the audit system is off, no
action is performed; -1 is returned and errno is set to EALREADY.
AUD_SETNEXT The caller issues the AUD_SETNEXT command to change only the "next"
audit file. If the auditing system is on, the file specified by npath is used as
the "next" audit file. cpath is ignored. If the "next" audit file specified does not
exist, it is created with the specified mode. Either an empty string or NULL
npath can be specified if the caller wants to designate that no "next" file be
available to the auditing system. If the auditing system is off, no action is per-
formed; -1 is returned, and errno is set to EALREADY.
AUD_SWITCH The caller issues the AUD_SWITCH command to cause auditing system to
switch audit files. If the auditing system is on, it uses the "next" file as the
new "current" audit file and sets the new "next" audit file to NULL. cpath ,
npath ,and mode are ignored. The auditing system begins writing to the new
"current" file. If the auditing system is off, no action is performed; -1 is
returned, and errno is set to EALREADY. If the auditing system is on and
