| 74 * FUNCTION: pkix_NameChainingChecker_Initialize | |
| 75 * DESCRIPTION: | |
| 76 * | |
| 77 * Creates a new CertChainChecker and stores it at "pChecker", where it will | |
| 78 * be used by pkix_NameChainingChecker_Check to check that the issuer name | |
| 79 * of the certificate matches the subject name in the checker's state. The | |
| 80 * X500Name pointed to by "trustedCAName" is used to initialize the checker's | |
| 81 * state. | |
| 82 * | |
| 83 * PARAMETERS: | |
| 84 * "trustedCAName" | |
| 85 * Address of X500Name representing the trusted CA Name used to | |
| 86 * initialize the state of this checker. Must be non-NULL. | |
| 87 * "pChecker" | |
| 88 * Address where object pointer will be stored. Must be non-NULL. | |
| 89 * "plContext" | |
| 90 * Platform-specific context pointer. | |
| 91 * THREAD SAFETY: | |
| 92 * Thread Safe (see Thread Safety Definitions in Programmer's Guide) | |
| 93 * RETURNS: | |
| 94 * Returns NULL if the function succeeds. | |
| 95 * Returns a CertChainChecker Error if the function fails in a non-fatal way. | |
| 96 * Returns a Fatal Error if the function fails in an unrecoverable way. | |
