-/* 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.

- * FUNCTION: PKIX_Initialize
- * DESCRIPTION:
- *
- * No PKIX_* types and functions should be used before this function is called
- * and returns successfully. This function should only be called once. If it
- * is called more than once, the behavior is undefined.
- *
- * NSS applications are expected to call NSS_Init, and need not know that
- * NSS will call this function (with "platformInitNeeded" set to PKIX_FALSE).
- * PKIX applications are expected instead to call this function with
- * "platformInitNeeded" set to PKIX_TRUE.
- *
- * This function initializes data structures critical to the operation of
- * libpkix. It also ensures that the API version (major.minor) desired by the
- * caller (the "desiredMajorVersion", "minDesiredMinorVersion", and
- * "maxDesiredMinorVersion") is compatible with the API version supported by
- * the library. As such, the library must support the "desiredMajorVersion"
- * of the API and must support a minor version that falls between
- * "minDesiredMinorVersion" and "maxDesiredMinorVersion", inclusive. If
- * compatibility exists, the function returns NULL and stores the library's
- * actual minor version at "pActualMinorVersion" (which may be greater than
- * "desiredMinorVersion"). If no compatibility exists, the function returns a
- * PKIX_Error pointer. If the caller wishes to specify that the largest
- * minor version available should be used, then maxDesiredMinorVersion should
- * be set to the macro PKIX_MAX_MINOR_VERSION (defined in pkixt.h).
- *
- * PARAMETERS:
- *  "platformInitNeeded"
- *      Boolean indicating whether the platform layer initialization code
- *      has previously been run, or should be called from this function.
- *  "desiredMajorVersion"
- *      The major version of the libpkix API the application wishes to use.
- *  "minDesiredMinorVersion"
- *      The minimum minor version of the libpkix API the application wishes
- *      to use.
- *  "maxDesiredMinorVersion"
- *      The maximum minor version of the libpkix API the application wishes
- *      to use.
- *  "pActualMinorVersion"
- *      Address where PKIX_UInt32 will be stored. Must be non-NULL.
- *  "pPlContext"
- *      Address at which platform-specific context pointer is stored. Must
- *      be non-NULL.
- * THREAD SAFETY:
- *  Not Thread Safe
- * RETURNS:
- *  Returns NULL if the function succeeds.
- *  Returns an Initialize Error if the function fails in a non-fatal way.
- *  Returns a Fatal Error if the function fails in an unrecoverable way.

- * FUNCTION: PKIX_ValidateChain
- * DESCRIPTION:
- *
- *  This function attempts to validate the CertChain that has been set in the

- *
- *  If "pVerifyTree" is non-NULL, a chain of VerifyNodes is created which

- * FUNCTION: PKIX_ValidateChain_NB
- * DESCRIPTION:
- *
- *  This function is the equivalent of PKIX_ValidateChain, except that it
- *  supports non-blocking I/O. When called with "pNBIOContext" pointing to NULL
- *  it initiates a new chain validation as in PKIX_ValidateChain, ignoring the
- *  value in all input variables except "params". If forced to suspend
- *  processing by a WOULDBLOCK return from some operation, such as a CertStore
- *  request, it stores the platform-dependent I/O context at "pNBIOContext" and
- *  stores other intermediate variables at "pCertIndex", "pAnchorIndex", 
- *  "pCheckerIndex", "pRevChecking", and "pCheckers".
- *
- *  When called subsequently with that non-NULL value at "pNBIOContext", it
- *  relies on those intermediate values to be untouched, and it resumes chain
- *  validation where it left off. Its behavior is undefined if any of the
- *  intermediate values was not preserved.
- *
- * PARAMETERS:
- *  "params"
- *      Address of ValidateParams used to validate CertChain. Must be non-NULL.
- *  "pCertIndex"
- *      The UInt32 value of the index to the Cert chain, indicating which Cert
- *      is currently being processed.
- *  "pAnchorIndex"
- *      The UInt32 value of the index to the Anchor chain, indicating which
- *      Trust Anchor is currently being processed.
- *  "pCheckerIndex"
- *      The UInt32 value of the index to the List of CertChainCheckers,
- *      indicating which Checker is currently processing.
- *  "pRevChecking"
- *      The Boolean flag indicating whether normal checking or revocation
- *      checking is occurring for the Cert indicated by "pCertIndex".
- *  "pCheckers"
- *      The address of the List of CertChainCheckers. Must be non-NULL.
- *  "pNBIOContext"
- *      The address of the platform-dependend I/O context. Must be a non-NULL
- *      pointer to a NULL value for the call to initiate chain validation.
- *  "pResult"
- *      Address where ValidateResult object pointer will be stored. Must be
- *      non-NULL.

- * FUNCTION: PKIX_BuildChain
- * DESCRIPTION:
- *
- *  If called with a NULL "state", this function attempts to build and validate
- *  a CertChain according to the ProcessingParams pointed to by "params", using
- *  an RFC 3280-compliant validation algorithm. If successful, this function
- *  returns NULL and stores the BuildResult at "pResult", which holds the built
- *  CertChain, as well as additional information, such as the policy tree and
- *  the target's public key. If unsuccessful, an Error is returned.
- *
- *  If the chain building is blocked by a CertStore using non-blocking I/O, this
- *  function stores platform-dependent non-blocking I/O context at
- *  "pNBIOContext", its state at "pState", and NULL at "pResult". The caller
- *  may be able to determine, in a platform-dependent way, when the I/O has
- *  completed. In any case, calling the function again with "pState" containing
- *  the returned value will allow the chain building to resume.
- *
- *  If chain building is completed, either successfully or unsuccessfully, NULL
- *  is stored at "pNBIOContext".
- *
- *  If "pVerifyTree" is non-NULL, a tree of VerifyNodes is created which
- *  tracks the results of the building. That is, each node of the tree either
- *  has a NULL Error component, or it is a leaf node and it contains an Error
- *  which indicates why the chain building could not proceed on this branch.
- *
- * PARAMETERS:
- *  "params"
- *      Address of ProcessingParams used to build and validate CertChain.
- *      Must be non-NULL.
- *  "pNBIOContext"
- *      Address where platform-dependent information is store if the build
- *      is suspended waiting for non-blocking I/O. Must be non-NULL.
- *  "pState"
- *      Address of BuildChain state. Must be NULL on initial call, and the
- *      value previously returned on subsequent calls.
- *  "pResult"
- *      Address where object pointer will be stored. Must be non-NULL.
- *  "pVerifyTree"
- *      Address where a VerifyTree is stored, if non-NULL.
