libtraceevent(3) ================ NAME ---- tep_get_page_size, tep_set_page_size - Get / set the size of a memory page on the machine, where the trace is generated 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)); -- FILES ----- [verse] -- *event-parse.h* Header file to include in order to have access to the library APIs. *-ltraceevent* Linker switch to add when building a program that uses the library. -- SEE ALSO -------- _libtraceevent(3)_, _trace-cmd(1)_ AUTHOR ------ [verse] -- *Steven Rostedt* <rostedt@goodmis.org>, author of *libtraceevent*. *Tzvetomir Stoyanov* <tz.stoyanov@gmail.com>, author of this man page. -- REPORTING BUGS -------------- Report bugs to <linux-trace-devel@vger.kernel.org> LICENSE ------- libtraceevent is Free Software licensed under the GNU LGPL 2.1 RESOURCES --------- https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git |
