Name
acct — switch process accounting on or off
Synopsis
#include <unistd.h>
int
acct( |
const char * |
filename); |
DESCRIPTION
When called with the name of an existing file as argument,
accounting is turned on, records for each terminating process
are appended to filename as it terminates. An
argument of NULL causes accounting to be turned off.
RETURN VALUE
On success, zero is returned. On error, −1 is
returned, and errno is set
appropriately.
ERRORS
- EACCES
-
Write permission is denied for the specified file,
or search permission is denied for one of the
directories in the path prefix of filename (see also
path_resolution(7)),
or filename is
not a regular file.
- EFAULT
-
filename
points outside your accessible address space.
- EIO
-
Error writing to the file filename.
- EISDIR
-
filename is
a directory.
- ELOOP
-
Too many symbolic links were encountered in
resolving filename.
- ENAMETOOLONG
-
filename was
too long.
- ENFILE
-
The system limit on the total number of open files
has been reached.
- ENOENT
-
The specified filename does not exist.
- ENOMEM
-
Out of memory.
- ENOSYS
-
BSD process accounting has not been enabled when the
operating system kernel was compiled. The kernel
configuration parameter controlling this feature is
CONFIG_BSD_PROCESS_ACCT.
- ENOTDIR
-
A component used as a directory in filename is not in fact a
directory.
- EPERM
-
The calling process has insufficient privilege to
enable process accounting. On Linux the CAP_SYS_PACCT capability is
required.
- EROFS

filename
refers to a file on a read-only file system.
- EUSERS
-
There are no more free file structures or we ran out
of memory.

NOTES
No accounting is produced for programs running when a
crash occurs. In particular, nonterminating processes are
never accounted for.
