NAME

       function::user_long - Retrieves a long value stored in user space

SYNOPSIS

           user_long: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. 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).
