инициализировать библиотеку (initialize library)
Имя (Name)
pfm_initialize - initialize library
Синопсис (Synopsis)
#include <perfmon/pfmlib.h>
int pfm_initialize(void);
Описание (Description)
This is the first function that a program must call otherwise the
library will not operate. This function probes the underlying
hardware looking for valid PMU event tables to activate.
Multiple distinct PMU tables may be activated at the same time.
The function must be called only once. If the function is called
more than once, it does not execute the initialization multiple
times, it simply returns the same value as for the first call.
Возврат (Return)
The function returns whether or not it was successful, i.e., at
least one PMU was activated. A return value of PFMLIB_SUCCESS
indicates success, otherwise the value is an error code.
Ошибки (Error)
PFMLIB_ERR_NOTSUPP
No PMU was activated.
