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.
