Prokee Module: file

The module file provides platform independent functions for file access.

File Access Modes

The following file access modes can be used:

Mode	Direction	Info
r	input	Opens a existing file for input. Fails, if the file does not exist.
r+	input and output	Opens a existing file for input and output. Fails, if the file does not exist.
w	output	Opens a file for output. The file will be created, if it does not jet exist. The contents of an existing file will be discarded.
w+	input and output	Opens a file for input and output. The file will be created, if it does not jet exist. The contents of an existing file will be discarded.
a	output	Opens a file for output. The file will be created, if it does not jet exist. The output will be appended on the end of the file.
a+	input and output	Opens a file for input and output. The file will be created, if it does not jet exist. The output will be appended on the end of the file.
rt r+t rt+ wt w+t wt+ at a+t at+	-	Adding a t, specifies text-mode. This is the default mode, so adding a t has no effect. This mode is system specific and should only be used for text files. Text-mode is useful, if files are shared between different applications on the same operating system.
rb r+b rb+ wb w+b wb+ ab a+b ab+	-	When adding a b, the file will be opened in binary-mode. When using this mode, every byte is read (or written) as it is indeed stored in the file. This mode should be used when files are shared between different operating systems.
