| * FUNCTION: pkix_ExpirationChecker_Initialize |
| * DESCRIPTION: |
| * |
| * Creates a new CertChainChecker and stores it at "pChecker", where it will |
| * used by pkix_ExpirationChecker_Check to check that the certificate has not |
| * expired with respect to the Date pointed to by "testDate." If "testDate" |
| * is NULL, then the CertChainChecker will check that a certificate has not |
| * expired with respect to the current date and time. |
| * |
| * PARAMETERS: |
| * "testDate" |
| * Address of Date representing the point in time at which the cert is to |
| * be validated. If "testDate" is NULL, the current date and time is used. |
| * "pChecker" |
| * Address where object pointer will be 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 a CertChainChecker Error if the function fails in a non-fatal way. |
| * Returns a Fatal Error if the function fails in an unrecoverable way. |
