PAPI_num_counters(3)						       PAPI						      PAPI_num_counters(3)

NAME

       PAPI_num_counters -

       Get the number of hardware counters available on the system.

SYNOPSIS

Detailed Description
       @par C Interface:
       int PAPI_num_counters( void );

       Postcondition:
	   Initializes the library to PAPI_HIGH_LEVEL_INITED if necessary.

       Return values:
	   PAPI_EINVAL papi.h is different from the version used to compile the PAPI library.
	   PAPI_ENOMEM Insufficient memory to complete the operation.
	   PAPI_ESYS A system or C library call failed inside PAPI, see the errno variable.

       Examples:

	   * int num_hwcntrs;
	   * //  The installation does not support PAPI
	   * if ((num_hwcntrs = PAPI_num_counters()) < 0 )
	   *   handle_error(1);
	   * //  The installation supports PAPI, but has no counters
	   * if ((num_hwcntrs = PAPI_num_counters()) == 0 )
	   *   fprintf(stderr,"Info:: This machine does not provide hardware counters.0);
	   *

       PAPI_num_counters() returns the optimal length of the values array for the high level functions. This value corresponds to the number of
       hardware counters supported by the current CPU component.

       Note:
	   This function only works for the CPU component. To determine the number of counters on another component, use the low level
	   PAPI_num_cmp_hwctrs().
