Parameter ticket: The download ticket.

Parameter setupContext: User defined. Passed as a parameter to the setupCallback.

Parameter evaluate: Called after SecTrustEvaluate has been called for a signer if the result was not trusted. This allows the developer to query the user as to whether or not to trust the signer. Returns a SecTrustResultType

Parameter evaluateContext: User defined. Passed as a parameter to the evaluate callback.

Parameter downloadRef: The returned reference.

Returns: Returns errSecureDownloadInvalidTicket if the ticket was invalid. Otherwise see “Security Error Codes” (SecBase.h). .

Safety

• ticket might not allow None.
• setup must be implemented correctly.
• setup_context must be a valid pointer.
• evaluate must be implemented correctly.
• evaluate_context must be a valid pointer.
• download_ref must be a valid pointer.
