NAME
auditsvc − write audit log to specified file descriptor
SYNOPSIS
cc [
flag ... ] file... -lbsm
-lsocket -lnsl -lintl [ library
... ]
#include <sys/param.h>
#include <bsm/audit.h>
int auditsvc(int fd, int limit);
DESCRIPTION
The auditsvc() function specifies the audit log file to the kernel. The kernel writes audit records to this file until an exceptional condition occurs and then the call returns. The fd argument is a file descriptor that identifies the audit file. Applications should open this file for writing before calling auditsvc().
The limit argument specifies the number of free blocks that must be available in the audit file system, and causes auditsvc() to return when the free disk space on the audit filesystem drops below this limit. Thus, the invoking program can take action to avoid running out of disk space.
The auditsvc() function does not return until one of the following conditions occurs:
|
• |
The process receives a signal that is not blocked or ignored. | ||
|
• |
An error is encountered writing to the audit log file. | ||
|
• |
The minimum free space (as specified by limit), has been reached. |
RETURN VALUES
The auditsvc() function returns only on an error.
ERRORS
The
auditsvc() function will fail if:
EAGAIN
The descriptor referred to a stream, was marked for System V-style non-blocking I/O, and no data could be written immediately.
|
EBADF |
The fd argument is not a valid descriptor open for writing. | ||
|
EBUSY |
A second process attempted to perform this call. | ||
|
EFBIG |
An attempt was made to write a file that exceeds the process’s file size limit or the maximum file size. | ||
|
EINTR |
The call is forced to terminate prematurely due to the arrival of a signal whose SV_INTERRUPT bit in sv_flags is set (see sigvec(3UCB)). The signal(3C) function sets this bit for any signal it catches. |
EINVAL
Auditing is disabled (see auditon(2)), or the fd argument does not refer to a file of an appropriate type (regular files are always appropriate.)
|
EIO |
An I/O error occurred while reading from or writing to the file system. |
ENOSPC
The user’s quota of disk blocks on the file system containing the file has been exhausted; audit filesystem space is below the specified limit; or there is no free space remaining on the file system containing the file.
|
ENXIO |
A hangup occurred on the stream being written to. |
|||
|
EPERM |
The process’s effective user ID is not superuser. |
EWOULDBLOCK
The file was marked for 4.2 BSD-style non-blocking I/O, and no data could be written immediately.
USAGE
Only processes with an effective user ID of superuser can execute this call successfully.
