DESCRIPTION
-----------
-The _tep_get_long_size()_ function returns the size of a long integer on the machine,
-where the trace is generated. The _tep_ argument is trace event parser context.
+The _tep_get_page_size()_ function returns the size of a memory page on
+the machine, where the trace is generated. The _tep_ argument is trace
+event parser context.
-The _tep_set_long_size()_ function sets the size of a long integer on the machine,
-where the trace is generated. The _tep_ argument is trace event parser context.
-The _long_size_ is the size of a long integer, in bytes.
+The _tep_set_page_size()_ function stores in the _tep_ context the size of a
+memory page on the machine, where the trace is generated.
+The _tep_ argument is trace event parser context.
+The _page_size_ argument is the size of a memory page, in bytes.
RETURN VALUE
------------
-The _tep_get_long_size()_ function returns the size of a long integer on the machine,
-where the trace is generated, in bytes.
+The _tep_get_page_size()_ function returns size of the memory page, in bytes.
