michael@0:  * FUNCTION: pkix_ExpirationChecker_Initialize
michael@0:  * DESCRIPTION:
michael@0:  *
michael@0:  *  Creates a new CertChainChecker and stores it at "pChecker", where it will
michael@0:  *  used by pkix_ExpirationChecker_Check to check that the certificate has not
michael@0:  *  expired with respect to the Date pointed to by "testDate." If "testDate"
michael@0:  *  is NULL, then the CertChainChecker will check that a certificate has not
michael@0:  *  expired with respect to the current date and time.
michael@0:  *
michael@0:  * PARAMETERS:
michael@0:  *  "testDate"
michael@0:  *      Address of Date representing the point in time at which the cert is to
michael@0:  *      be validated. If "testDate" is NULL, the current date and time is used.
michael@0:  *  "pChecker"
michael@0:  *      Address where object pointer will be stored. Must be non-NULL.
michael@0:  *  "plContext"
michael@0:  *      Platform-specific context pointer.
michael@0:  * THREAD SAFETY:
michael@0:  *  Thread Safe (see Thread Safety Definitions in Programmer's Guide)
michael@0:  * RETURNS:
michael@0:  *  Returns NULL if the function succeeds.
michael@0:  *  Returns a CertChainChecker Error if the function fails in a non-fatal way.
michael@0:  *  Returns a Fatal Error if the function fails in an unrecoverable way.
