0019 DESCRIPTION
0020 -----------
0021 The _tep_get_page_size()_ function returns the size of a memory page on
0022 the machine, where the trace is generated. The _tep_ argument is trace
0023 event parser context.
0024
0025 The _tep_set_page_size()_ function stores in the _tep_ context the size of a
0026 memory page on the machine, where the trace is generated.
0027 The _tep_ argument is trace event parser context.
0028 The _page_size_ argument is the size of a memory page, in bytes.
0029
0030 RETURN VALUE
0031 ------------
0032 The _tep_get_page_size()_ function returns size of the memory page, in bytes.
