Description
This function may be used to obtain a pointer to the internal structures maintained by PXPIO.
Note:
The values contained within this structure should not be modified by an outside application. Any attempt to do so may result in file corruption and/or cause the application to become unstable.
If successful, this function will return valid pointer; otherwise, it will return null.
Warning!
Passing a bad or invalid file handle can cause unpredictable results that may lead to abnormal termination.
