Hello,
I am trying to compute the percentage in a script as shown below:
PerCover=`echo "scale=2 ; 100 \* ($InputCover/$Total)" | bc`
However the PerCover value is blank/null. What do I need to do differently?
Thanks for your input!

cpc_access(3CPC)cpc_access(3CPC)NAME
cpc_access - test access CPU performance counters
SYNOPSIS
cc [ flag... ] file... -lcpc [ library... ]
#include <libcpc.h>
int cpc_access(void);
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.
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.
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 cor-
rectly installed.

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 This function is obsolete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.
