SYNOPSIS

10           user_ulong_warn:long(addr:long)
11

ARGUMENTS

13       addr
14           the user space address to retrieve the unsigned long from
15

DESCRIPTION

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