NAME    [Toc]    [Back]

     acct - enable or disable process accounting

SYNOPSIS    [Toc]    [Back]

     #include <unistd.h>

     acct(const char *file);

DESCRIPTION    [Toc]    [Back]

     The acct() call enables or disables the collection of system
     records.   If file is NULL, accounting is disabled.  If file
is an existing,
 null-terminated pathname, record collection is  enabled
and for every
     process  initiated  which terminates under normal conditions
an accounting
     record is appended to file.  Abnormal conditions of termination are reboots
 or other fatal system problems.  Records for processes
which never
     terminate can not be produced by acct().

     For more information on the record structure used by acct(),
     /usr/include/sys/acct.h and acct(5).

     This call is permitted only to the superuser.

NOTES    [Toc]    [Back]

     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 VALUES    [Toc]    [Back]

     On  error  -1 is returned.  The file must exist and the call
may be exercised
 only by the superuser.
