Syntax: void Clearstatcache (void);

Description:

The use of stat () and Lstat () is quite resource consuming, so the result of any status function call is stored so that it can be used the next time a call with the same file name is used. If you want to force a new state check (check), for example: If the file is present (maximally) to check a lot of time, and may change or disappear, use this function to clear the result of the last call from the memory.

The affected functions include: stat (), Lstat (), file_exists (), is_writeable (), is_readable (), is_executable (), Is_file (), Is_dir (), Is_link (), Filectime (), Fileatime (), Filemtime (), Fileinode (), filegroup (), Fileowner (), filesize (), filetype (), and fileperms ().
