cpc_access

- test access CPU performance counters

Synopsis

cc [ flag... ] file... -lcpc [ library... ]
#include <libcpc.h>

int cpc_access(void);

Description

Access to CPU performance counters is possible only on systems where the appropriate hardware exists and is correctly configured. The cpc_access() function must be used to determine if the hardware exists and is accessible on the platform before any of the interfaces that use the counters are invoked.

When the hardware is available, access to the per-process counters is always allowed to the process itself, and allowed to other processes mediated using the existing security mechanisms of /proc.

Return Values

Upon successful completion, cpc_access() returns 0. Otherwise, it returns -1 and sets errno to indicate the error.

By default, two common errno values are decoded and cause the library to print an error message using its reporting mechanism. See cpc_seterrfn(3CPC) for a description of how this behavior can be modified.

Errors

The cpc_access() function will fail if:

EAGAIN

Another process may be sampling system-wide CPU statistics.

ENOSYS

CPU performance counters are inaccessible on this machine. This error can occur when the machine supports CPU performance counters, but some software components are missing. Check to see that all CPU Performance Counter packages have been correctly installed.

Attributes

See attributes(5) for descriptions of the following attributes:

ATTRIBUTE TYPE

MT-Level
MT-Safe

Obsolete

Notes

The cpc_access() function exists for binary compatibility only. Source containing this function will not compile. This function is obsolete and might be removed in a future release. Applications should use cpc_open(3CPC) instead.
