- * FUNCTION: pkix_pl_OcspResponse_Create
- * DESCRIPTION:
- *
- *  This function transmits the OcspRequest pointed to by "request" and obtains
- *  an OcspResponse, which it stores at "pOcspResponse". If the HTTPClient
- *  supports non-blocking I/O this function may store a non-NULL value at
- *  "pNBIOContext" (the WOULDBLOCK condition). In that case the caller should
- *  make a subsequent call with the same value in "pNBIOContext" and
- *  "pOcspResponse" to resume the operation. Additional WOULDBLOCK returns may
- *  occur; the caller should persist until a return occurs with NULL stored at
- *  "pNBIOContext".
- *
- *  If a SEC_HttpClientFcn "responder" is supplied, it is used as the client
- *  to which the OCSP query is sent. If none is supplied, the default responder
- *  is used.
- *
- *  If an OcspResponse_VerifyCallback "verifyFcn" is supplied, it is used to
- *  verify the Cert received from the responder as the signer. If none is
- *  supplied, the default verification function is used.
- *
- *  The contents of "request" are ignored on calls subsequent to a WOULDBLOCK
- *  return, and the caller is permitted to supply NULL.
- *
- * PARAMETERS
- *  "request"
- *      Address of the OcspRequest for which a response is desired.
- *  "responder"
- *      Address, if non-NULL, of the SEC_HttpClientFcn to be sent the OCSP
- *      query.
- *  "verifyFcn"
- *      Address, if non-NULL, of the OcspResponse_VerifyCallback function to be
- *      used to verify the Cert of the OCSP responder.
- *  "pNBIOContext"
- *      Address at which platform-dependent information is stored for handling
- *      of non-blocking I/O. Must be non-NULL.
- *  "pOcspResponse"
- *      The address where the created OcspResponse is stored. Must be non-NULL.
- *  "plContext"
- *      Platform-specific context pointer.
- * THREAD SAFETY:
- *  Thread Safe (see Thread Safety Definitions in Programmer's Guide)
- * RETURNS:
- *  Returns NULL if the function succeeds.
- *  Returns an OcspResponse Error if the function fails in a non-fatal way.
- *  Returns a Fatal Error if the function fails in an unrecoverable way.

- * FUNCTION: pkix_pl_OcspResponse_GetStatusForCert
- * DESCRIPTION:
- *
- *  This function checks the revocation status of the Cert for which the
- *  OcspResponse was obtained, storing PKIX_TRUE at "pPassed" if the Cert has
- *  not been revoked and PKIX_FALSE otherwise.
- *
- * PARAMETERS
- *  "response"
- *      The address of the OcspResponse whose certificate status is to be
- *      retrieved. Must be non-NULL.
- *  "pPassed"
- *      Address at which the Boolean result is stored. Must be non-NULL.
- *  "pReturnCode"
- *      Address at which the SECErrorCodes result is stored. Must be non-NULL.
- *  "plContext"
- *      Platform-specific context pointer.
- * THREAD SAFETY:
- *  Thread Safe (see Thread Safety Definitions in Programmer's Guide)
- * RETURNS:
- *  Returns NULL if the function succeeds.
- *  Returns an OcspResponse Error if the function fails in a non-fatal way.
- *  Returns a Fatal Error if the function fails in an unrecoverable way.
