Structure SilcSFTPFilesystemOps NAME
        typedef struct SilcSFTPFilesystemOpsStruct { ... }
                         *SilcSFTPFilesystemOps;
DESCRIPTION
        This structure defines the generic filesystem access.  When the
        filesystem is accessed these functions are called to do the requested
        filesystem operation.  The level that implements the actual filesystem
        must fill this structure with the callback functions providing the
        access to the filesystem.
