| 90 * | |
| 91 * Determines whether the Cert pointed to by "cert" matches the basic | |
| 92 * constraints criterion using the basic constraints field of the | |
| 93 * ComCertSelParams pointed to by "params". If the basic constraints field is | |
| 94 * -1, no basic constraints check is done and the Cert is considered to match | |
| 95 * the basic constraints criterion. If the Cert does not match the basic | |
| 96 * constraints criterion, an Error pointer is returned. | |
| 97 * | |
| 98 * In order to match against this criterion, there are several possibilities. | |
| 99 * | |
| 100 * 1) If the criterion's minimum path length is greater than or equal to zero, | |
| 101 * a certificate must include a BasicConstraints extension with a pathLen of | |
| 102 * at least this value. | |
| 103 * | |
| 104 * 2) If the criterion's minimum path length is -2, a certificate must be an | |
| 105 * end-entity certificate. | |
| 106 * | |
| 107 * 3) If the criterion's minimum path length is -1, no basic constraints check | |
| 108 * is done and all certificates are considered to match this criterion. | |
| 109 * | |
| 110 * PARAMETERS: | |
| 111 * "params" | |
| 112 * Address of ComCertSelParams whose basic constraints field is used. | |
| 113 * Must be non-NULL. | |

| 117 * Address of PKIX_Boolean that returns the match result. | |
| 118 * "plContext" | |
| 119 * Platform-specific context pointer. | |
| 120 * OUTPUT PARAMETERS ON FAILURE: | |
| 121 * If the function returns a failure, | |
| 122 * the output parameters of this function are undefined. | |
| 123 * THREAD SAFETY: | |
| 124 * Conditionally Thread Safe | |
| 125 * (see Thread Safety Definitions in Programmer's Guide) | |

| 1100 * | |
| 1101 * This default match function determines whether the specified Cert pointed | |
| 1102 * to by "cert" matches the criteria of the CertSelector pointed to by | |
| 1103 * "selector". If the Cert does not match the CertSelector's | |
| 1104 * criteria, an error will be thrown. | |
| 1105 * | |
| 1106 * This default match function understands how to process the most common | |
| 1107 * parameters. Any common parameter that is not set is assumed to be disabled, | |
| 1108 * which means this function will select all certificates without regard to | |
| 1109 * that particular disabled parameter. For example, if the SerialNumber | |
| 1110 * parameter is not set, this function will not filter out any certificate | |
| 1111 * based on its serial number. As such, if no parameters are set, all are | |
| 1112 * disabled and any certificate will match. If a parameter is disabled, its | |
| 1113 * associated PKIX_ComCertSelParams_Get* function returns a default value. | |
| 1114 * That value is -1 for PKIX_ComCertSelParams_GetBasicConstraints and | |
| 1115 * PKIX_ComCertSelParams_GetVersion, 0 for PKIX_ComCertSelParams_GetKeyUsage, | |
| 1116 * and NULL for all other Get functions. | |
| 1117 * | |
| 1118 * PARAMETERS: | |
| 1119 * "selector" | |
| 1120 * Address of CertSelector whose MatchCallback logic and parameters are | |
| 1121 * to be used. Must be non-NULL. | |
| 1122 * "cert" | |
| 1123 * Address of Cert that is to be matched using "selector". | |

| 1551 * DESCRIPTION: | |
| 1552 * | |
| 1553 * This function applies the selector pointed to by "selector" to each Cert, | |
| 1554 * in turn, in the List pointed to by "before", and creates a List containing | |
| 1555 * all the Certs that matched, or passed the selection process, storing that | |
| 1556 * List at "pAfter". If no Certs match, an empty List is stored at "pAfter". | |
| 1557 * | |
| 1558 * The List returned in "pAfter" is immutable. | |
| 1559 * | |
| 1560 * PARAMETERS: | |
| 1561 * "selector" | |
| 1562 * Address of CertSelelector to be applied to the List. Must be non-NULL. | |
| 1563 * "before" | |
| 1564 * Address of List that is to be filtered. Must be non-NULL. | |
| 1565 * "pAfter" | |
| 1566 * Address at which resulting List, possibly empty, is stored. Must be | |
| 1567 * non-NULL. | |
| 1568 * "plContext" | |
| 1569 * Platform-specific context pointer. | |
| 1570 * THREAD SAFETY: | |
| 1571 * Thread Safe (see Thread Safety Definitions in Programmer's Guide) | |
| 1572 * RETURNS: | |
| 1573 * Returns NULL if the function succeeds. | |
| 1574 * Returns a CertSelector Error if the function fails in a non-fatal way. | |
| 1575 * Returns a Fatal Error if the function fails in an unrecoverable way. | |
