|
|
Invoking the <systemitem>stat</systemitem> or
|
|
<systemitem>lstat</systemitem> system call on most systems is
|
|
quite expensive. Therefore, the result of the last call to any of
|
|
the status functions (listed below) is stored for use on the next
|
|
such call using the same filename. If you wish to force a new
|
|
status check, for instance if the file is being checked many
|
|
times and may change or disappear, use this function to clear the
|
|
results of the last call from memory.
