NAME

acct - switch process accounting on or off  

SYNOPSIS

#include <unistd.h>

int acct(const char *filename);

Feature Test Macro Requirements for glibc (see feature_test_macros(7)):

acct(): _BSD_SOURCE || (_XOPEN_SOURCE && _XOPEN_SOURCE < 500)  

DESCRIPTION

The acct() system call enables or disables process accounting. If called with the name of an existing file as its argument, accounting is turned on, and 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.
 

CONFORMING TO

SVr4, 4.3BSD (but not POSIX).  

NOTES

No accounting is produced for programs running when a system crash occurs. In particular, non-terminating processes are never accounted for.

The structure of the records written to the accounting file is described in acct(5).
