Switched to POCO library for unified platform/library interface. Deprecated the external module API. It was creating more problems than solving. Removed most built-in libraries in favor of system libraries for easier maintenance. Cleaned and secured code with help from static analyzers.

|
|
* wceex_clock - report CPU time used
|
|
*
|
|
* Description:
|
|
*
|
|
* The clock() function shall return the implementation's best approximation to
|
|
* the processor time used by the process since the beginning of
|
|
* an implementation-defined era related only to the process invocation.
|
|
*
|
|
* Windows CE specific:
|
|
* CLOCKS_PER_SEC is defined in <time.h> available in Windows CE SDK.
|
|
*
|
|
* Return value:
|
|
*
|
|
* To determine the time in seconds, the value returned by clock() should be
|
|
* divided by the value of the macro CLOCKS_PER_SEC.
|
|
* CLOCKS_PER_SEC is defined to be one million in <time.h>.
|
|
* If the processor time used is not available or its value cannot be represented,
|
|
* the function shall return the value ( clock_t)-1.
|
|
*
|
|
* Reference:
|
|
*
|
|
* IEEE Std 1003.1-2001
|

* The GNU C Library Manual
