libtraceevent(3) ================ NAME ---- tep_get_cpus, tep_set_cpus - Get / set the number of CPUs, which have a tracing buffer representing it. Note, the buffer may be empty. SYNOPSIS -------- [verse] -- *#include * int *tep_get_cpus*(struct tep_handle pass:[*]_tep_); void *tep_set_cpus*(struct tep_handle pass:[*]_tep_, int _cpus_); -- DESCRIPTION ----------- The _tep_get_cpus()_ function gets the number of CPUs, which have a tracing buffer representing it. The _tep_ argument is trace event parser context. The _tep_set_cpus()_ function sets the number of CPUs, which have a tracing buffer representing it. The _tep_ argument is trace event parser context. The _cpu_ argument is the number of CPUs with tracing data. RETURN VALUE ------------ The _tep_get_cpus()_ functions returns the number of CPUs, which have tracing data recorded. EXAMPLE ------- [source,c] -- #include ... struct tep_handle *tep = tep_alloc(); ... tep_set_cpus(tep, 5); ... printf("We have tracing data for %d CPUs", tep_get_cpus(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* , author of *libtraceevent*. *Tzvetomir Stoyanov* , author of this man page. -- REPORTING BUGS -------------- Report bugs to 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
