| SYNOPSIS |
| -------- |
| [verse] |
| -- |
| *#include <event-parse.h>* |
| |
| int *tep_get_page_size*(struct tep_handle pass:[*]_tep_); |
| void *tep_set_page_size*(struct tep_handle pass:[*]_tep_, int _page_size_); |

| DESCRIPTION |
| ----------- |
| 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_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_page_size()_ function returns size of the memory page, in bytes. |
| |
| EXAMPLE |
| ------- |
| [source,c] |
| -- |
| #include <unistd.h> |
| #include <event-parse.h> |
| ... |
| struct tep_handle *tep = tep_alloc(); |
| ... |
| int page_size = getpagesize(); |
| |
| tep_set_page_size(tep, page_size); |
| |
| printf("The page size for this machine is %d\n", tep_get_page_size(tep)); |
