nanospin_calibrate()

QNX SDP8.0C Library ReferenceAPIDeveloper

Calibrate before calling nanospin*()

Synopsis:

#include <time.h>

int nanospin_calibrate( int disable );

Arguments:

disable: 1 to disable interrupts during the call to nanospin_calibrate(), or 0 to enable them.

Library:

libc

Use the -l c option to qcc to link against this library. This library is usually included automatically.

Description:

Note:

The nanospin_*() functions have been reimplemented in terms of ClockCycles(), and consequently nanospin_calibrate() is no longer required. All it does now is return EOK.

Returns:

This function always returns EOK.

Classification:

QNX OS


Safety:
Cancellation point	No
Signal handler	Yes
Thread	Yes
