NAME

       function::user_ulong_error - Retrieves a unsigned long value stored in user space

SYNOPSIS

           user_ulong_error: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. If the user space data is
       not accessible, an error will occur. 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).
