FUNCT...ULONG(3stap) String and data retrieving fun FUNCT...ULONG(3stap)

NAME         top

       function::user_ulong_warn - Retrieves an unsigned long value
       stored in user space

SYNOPSIS         top

           user_ulong_warn:long(addr:long)

ARGUMENTS         top

       addr
           the user space address to retrieve the unsigned long from

DESCRIPTION         top

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