KDK_RTI_GET_CPU_CURRENT_USAGE(3)                      Library Functions Manual

NAME
       kdk_rti_get_cpu_current_usage - <?><?>CPU<?><?><?><?><?>

SYNOPSIS
       #include <libkyrtinfo.h>

       extern float kdk_rti_get_cpu_current_usage();

       Link with -lkyrtinfo.

Detailed Description
       The main function of the interface is to obtain the instantaneous CPU
       usage rate.

RETURN VALUE
       On success, returns the instantaneous CPU usage rate of type float.

       On error, return 0.

EXAMPLES
       #include "libkyrtinfo.h"
       #include <stdio.h>

       int main()
