DESCRIPTION

16       Returns the long value from a given user space address. Returns zero
17       when user space data is not accessible and warns about the failure (but
18       does not error). Note that the size of the long depends on the
19       architecture of the current user space task (for those architectures
20       that support both 64/32 bit compat tasks).
