NAMEacct() — enable or disable process accounting DESCRIPTIONThe acct() system call enables or disables the system's process accounting routine. If the routine is enabled, an accounting record is written on an accounting file for each process that terminates. Termination can be caused by one of two things: an exit() call or a signal (see exit(2) and signal(5)). The calling process must have the ACCOUNTING privilege to use this call. path points to a path name naming the accounting file. The accounting file format is described in acct(4). The accounting routine is enabled if path is nonzero and no errors occur during the system call. It is disabled if path is zero and no errors occur during the system call. When the amount of free space on the file system containing the accounting file falls below a configurable threshold, the system prints a message on the console and disables process accounting. Another message is printed and the process accounting is re-enabled when the space reaches a second configurable threshold. If the size of the process accounting file reaches a configurable limit, records for processes terminating after that point will be silently lost. However, in that case the turnacct command would still sense that process accounting is still enabled. This loss of records can be prevented with the ckpacct command. ckpacct and turnacct are described in acctsh(1M)). Security RestrictionsSome or all of the actions associated with this system call require the ACCOUNTING privilege. Processes owned by the superuser have this privilege. Processes owned by other users may have this privilege, depending on system configuration. See privileges(5) for more information about privileged access on systems that support fine-grained privileges. RETURN VALUEacct() returns the following values:
ERRORSIf acct() fails, errno is set to one of the following values.
