acct(5) [bsd man page]

ACCT(5) 							File Formats Manual							   ACCT(5)

NAME
acct - execution accounting file SYNOPSIS
#include <sys/acct.h> DESCRIPTION
The acct(2) system call arranges for entries to be made in an accounting file for each process that terminates. The accounting file is a sequence of entries whose layout, as defined by the include file is: If the process was created by an execve(2), the first 10 characters of the filename appear in ac_comm. The accounting flag contains bits indicating whether execve(2) was ever accomplished, and whether the process ever had super-user privileges. SEE ALSO

NAME
acct - turn accounting on or off SYNOPSIS
acct(file) char *file; DESCRIPTION
The system is prepared to write a record in an accounting file for each process as it terminates. This call, with a null-terminated string naming an existing file as argument, turns on accounting; records for each terminating process are appended to file. An argument of 0 causes accounting to be turned off. The accounting file format is given in acct(5). This call is permitted only to the super-user. NOTES
Accounting is automatically disabled when the file system the accounting file resides on runs out of space; it is enabled when space once again becomes available. RETURN VALUE
On error -1 is returned. The file must exist and the call may be exercised only by the super-user. It is erroneous to try to turn on accounting when it is already on. ERRORS
Acct will fail if one of the following is true: [EPERM] The caller is not the super-user. [ENOTDIR] A component of the path prefix is not a directory. [EINVAL] The pathname contains a character with the high-order bit set. [ENAMETOOLONG] A component of a pathname exceeded 255 characters, or an entire path name exceeded 1023 characters. [ENOENT] The named file does not exist. [EACCES] Search permission is denied for a component of the path prefix, or the path name is not a regular file. [ELOOP] Too many symbolic links were encountered in translating the pathname. [EROFS] The named file resides on a read-only file system. [EFAULT] File points outside the process's allocated address space. [EIO] An I/O error occurred while reading from or writing to the file system. SEE ALSO
acct(5), sa(8) BUGS
No accounting is produced for programs running when a crash occurs. In particular non-terminating programs are never accounted for. 4th Berkeley Distribution May 22, 1986 ACCT(2)
