int tep_get_page_size(struct tep_handle *tep);
void tep_set_page_size(struct tep_handle *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.

...


        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));
