acct(2)                          System Calls                          acct(2)

       acct - enable or disable process accounting

       #include <unistd.h>

       int acct(const char *path);

       The  acct()  function enables or disables the system process accounting
       routine. If the routine is enabled, an accounting record will be  writ-
       ten  in an accounting file for each process that terminates. The termi-
       nation of a process can be caused by either an exit(2) call or  a  sig-
       nal(3C)). The effective user ID of the process calling acct() must have
       the appropriate privileges.

       The path argument points to the pathname of the accounting file,  whose
       file format is described on the acct.h(3HEAD) manual page.

       The  accounting  routine  is  enabled if path is non-zero and no errors
       occur during the function. It is disabled if path is  (char *)NULL  and
       no errors occur during the function.

       Upon  successful  completion,  0 is returned. Otherwise, -1 is returned
       and errno is set to indicate the error.

       The acct() function will fail if:

       EACCES                  The file named by path is not an ordinary file.

                               exceeds  {NAME_MAX} while _POSIX_NO_TRUNC is in
