DirOpen (FB; Prefix fildop) ¶ FUNCTION_BLOCK DirOpen EXTENDS CBM.ETrig This function block opens a directory. The entries (files and sub-directories) of which should be read with the help of the function block ”FILE. DirList ”. The return value is a handle. There may be restrictions concerning the specification of the directory name, e.g. only capital letters allowed, for different targets. The function ”FILE. GetProperty ” shows these restrictions. InOut: Scope Name Type Comment Input sDirName CAA.FILENAME Directory name, absolute or relative path specification Output eError ERROR Local library error ID (0: no error; 5101: time out) hDir CAA.HANDLE Directory handle

DirRemove (FB; Prefix fildrm) ¶ FUNCTION_BLOCK DirRemove EXTENDS CBM.ETrigToA This function block deletes a directory. Contrary to the original CAA specification the directory may be removed even if it is opened via ”FILE. DirOpen ”. This behavior is dependent of the underlying operating system and file system. InOut: Scope Name Type Comment Input sDirName CAA.FILENAME Directory name xRecursive BOOL TRUE: Remove all files and sub-directories, FALSE: Directory is only deleted, if empty, i.e. if no files and sub-directories are left; otherwise an error will be dumped Output eError ERROR Local library error ID (5107 - FILE_NOT_EMPTY: Directory not empty; will be generated only if xRecursive = FALSE)

DirRename (FB; Prefix fildrn) ¶ FUNCTION_BLOCK DirRename EXTENDS CBM.ETrig This function block can be used to rename a directory and is optional for the different targets. Contrary to the original CAA specification the directory may be renamed even if it is opened via ”FILE. DirOpen ”. This behavior is dependent of the underlying operating system and file system. Whether this function block is implemented or not is explicitly stated and encoded in the return value of the function ”FILE. GetProperty ”. It is not recommended to use this function block to move files (it may work but is system dependent). Please use the appropriate function block ”FILE. Rename ” instead. InOut: Scope Name Type Comment Input sDirNameOld CAA.FILENAME Old directory name sDirNameNew CAA.FILENAME New directory name Output eError ERROR Local library error ID (0: no error; 5101: time out)
