## Detailed Description

Note: OS specific details for environment resolution.

Note: OS specific details for process timing.

Note: OS specific details as well as Gaudi details may not occur in this definition file, because this header is the used by both, the OS specific implementations and the gaudi specific implementation.

ModuleInfo: OS specific details to access at run-time the module configuration of the process.

Note: OS specific details for memory usage.

Entrypoints:

- remainingTime returns the time the process could still execute
- ellapsedTime: returns ellapsed time since program start
- kernelTime: returns the amount of time the process has spent in kernel mode
- userTime: returns the amount of time the process has spent in user mode
- cpuTime: returns kernel+user time

On Windows NT Time is expressed as the amount of time that has elapsed since midnight on January 1, 1601 at Greenwich, England.

On Unix time is expressed as the amount of time that has elapsed since midnight on January 1, 1970 at Greenwich, England.
