/* General
*
* Please refer to the libpkix Programmer's Guide for detailed information
* about how to use the libpkix library. Certain key warnings and notices from
* that document are repeated here for emphasis.
*
* All identifiers in this file (and all public identifiers defined in
* libpkix) begin with "PKIX_". Private identifiers only intended for use
* within the library begin with "pkix_".
*
* A function returns NULL upon success, and a PKIX_Error pointer upon failure.
*
* Unless otherwise noted, for all accessor (gettor) functions that return a
* PKIX_PL_Object pointer, callers should assume that this pointer refers to a
* shared object. Therefore, the caller should treat this shared object as
* read-only and should not modify this shared object. When done using the
* shared object, the caller should release the reference to the object by
* using the PKIX_PL_Object_DecRef function.
*
* While a function is executing, if its arguments (or anything referred to by
* its arguments) are modified, free'd, or destroyed, the function's behavior
* is undefined.

* XXX If this function is really only meant to be used by PKIX_Initialize,

*
* This function should NOT be called by applications. It is only meant to

* which in turn will call this function.

* This function initializes data structures critical to the operation of

* PARAMETERS:
* "platformInitNeeded"
* Boolean indicating whether platform initialization is to be called
* "useArenas"
