0019 DESCRIPTION
0020 -----------
0021 The _tep_get_cpus()_ function gets the number of CPUs, which have a tracing
0022 buffer representing it. The _tep_ argument is trace event parser context.
0023
0024 The _tep_set_cpus()_ function sets the number of CPUs, which have a tracing
0025 buffer representing it. The _tep_ argument is trace event parser context.
0026 The _cpu_ argument is the number of CPUs with tracing data.
0027
0028 RETURN VALUE
0029 ------------
0030 The _tep_get_cpus()_ functions returns the number of CPUs, which have tracing
0031 data recorded.
