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).
SEE ALSO
acct(5), sa(1)
DIAGNOSTICS
On error -1 is returned. The file must exist and the call may be exer‐
cised only by the super-user. It is erroneous to try to turn on ac‐
counting when it is already on.
BUGS
No accounting is produced for programs running when a crash occurs. In
particular nonterminating programs are never accounted for.
