NAME

6       tep_get_page_size, tep_set_page_size - Get / set the size of a memory
7       page on the machine, where the trace is generated
8

SYNOPSIS

10       #include <event-parse.h>
11
12       int tep_get_page_size(struct tep_handle *tep);
13       void tep_set_page_size(struct tep_handle *tep, int page_size);
14

DESCRIPTION

16       The tep_get_page_size() function returns the size of a memory page on
17       the machine, where the trace is generated. The tep argument is trace
18       event parser context.
19
20       The tep_set_page_size() function stores in the tep context the size of
21       a memory page on the machine, where the trace is generated. The tep
22       argument is trace event parser context. The page_size argument is the
23       size of a memory page, in bytes.
24

RETURN VALUE

26       The tep_get_page_size() function returns size of the memory page, in
27       bytes.

EXAMPLE

30           #include <unistd.h>
31           #include <event-parse.h>
32           ...
33           struct tep_handle *tep = tep_alloc();
34           ...
35                   int page_size = getpagesize();
36
37                   tep_set_page_size(tep, page_size);
38
39                   printf("The page size for this machine is %d\n", tep_get_page_size(tep));
