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

NAME
       function::userlongwarn - Retrieves a long value stored in user space

SYNOPSIS
           userlongwarn:long(addr:long)

ARGUMENTS
       addr
           the user space address to retrieve the long from

DESCRIPTION
       Returns the 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 long depends on the
       architecture of the current user space task (for those architectures
       that support both 64/32 bit compat tasks).
