acct - switch process accounting on or off
Standard C library (libc, -lc)
#include <unistd.h>
int acct(const char *_Nullable filename);
acct():
Since glibc 2.21:
_DEFAULT_SOURCE
In glibc 2.19 and 2.20:
_DEFAULT_SOURCE || (_XOPEN_SOURCE && _XOPEN_SOURCE < 500)
Up to and including glibc 2.19:
_BSD_SOURCE || (_XOPEN_SOURCE && _XOPEN_SOURCE < 500)
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.
On success, zero is returned. On error, -1 is returned, and errno is set to indicate the error.
SVr4, 4.3BSD (but not POSIX).
No accounting is produced for programs running when a system crash occurs. In particular, nonterminating processes are never accounted for.
The structure of the records written to the accounting file is described in acct(5).
