FUNCTION::USERULONG(3stString and data retrieving FUNCTION::USERULONG(3stap)

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

SYNOPSIS
           userulongwarn:long(addr:long)

ARGUMENTS
       addr
           the user space address to retrieve the unsigned long from

DESCRIPTION
       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).
