Provides implementation of functions to perform operations on the
Windows File System.
Exception handling is expected to be done by the callers:
- FileOpsLocalWindows class for operations done as the CURRENT user
- The wbadminhelper for operations done as ADMIN
Some exception handling is done on these functions but only to be able
to generate the PermissionDeniedError as it is used on further validations
on the admin code.
The functions can be divided in the next groups:
- Success functions: they are expected to succeed, they don't return any value
- Boolean functions: on success execution return a boolean value
- String functions: on success execution return a string
The functions will return the proper value on success or
generate an exception in case of failure.
The function names are self descriptive, however the function type
will be indicated on each of them using the criteria explained above
