    51  * FUNCTION: pkix_ExpirationChecker_Initialize

    52  * DESCRIPTION:

    53  *

    54  *  Creates a new CertChainChecker and stores it at "pChecker", where it will

    55  *  used by pkix_ExpirationChecker_Check to check that the certificate has not

    56  *  expired with respect to the Date pointed to by "testDate." If "testDate"

    57  *  is NULL, then the CertChainChecker will check that a certificate has not

    58  *  expired with respect to the current date and time.

    59  *

    60  * PARAMETERS:

    61  *  "testDate"

    62  *      Address of Date representing the point in time at which the cert is to

    63  *      be validated. If "testDate" is NULL, the current date and time is used.

    64  *  "pChecker"

    65  *      Address where object pointer will be stored. Must be non-NULL.

    66  *  "plContext"

    67  *      Platform-specific context pointer.

    68  * THREAD SAFETY:

    69  *  Thread Safe (see Thread Safety Definitions in Programmer's Guide)

    70  * RETURNS:

    71  *  Returns NULL if the function succeeds.

    72  *  Returns a CertChainChecker Error if the function fails in a non-fatal way.

    73  *  Returns a Fatal Error if the function fails in an unrecoverable way.
