public static int make(String path,
                       int perm,
                       long pool)

Create a new directory on the file system.

Parameters:

makeRecursive

public static int makeRecursive(String path,
                                int perm,
                                long pool)

Creates a new directory on the file system, but behaves like 'mkdir -p'. Creates intermediate directories as required. No error will be reported if PATH already exists.

Parameters:

path - the path for the directory to be created. (use / on all systems)

public static int remove(String path,
                         long pool)

Remove directory from the file system.

tempGet

public static String tempGet(long pool)

Find an existing directory suitable as a temporary storage location.

Parameters:

pool - The pool to use for any necessary allocations.

Returns:

The temp directory. This function uses an algorithm to search for a directory that an an application can use for temporary storage. Once such a directory is found, that location is cached by the library. Thus, callers only pay the cost of this algorithm once if that one time is successful.

                       long thedir)

Read the next entry from the specified directory.
