+/* General
+ *
+ * Please refer to the libpkix Programmer's Guide for detailed information
+ * about how to use the libpkix library. Certain key warnings and notices from
+ * that document are repeated here for emphasis.
+ *
+ * All identifiers in this file (and all public identifiers defined in
+ * libpkix) begin with "PKIX_". Private identifiers only intended for use
+ * within the library begin with "pkix_".
+ *
+ * A function returns NULL upon success, and a PKIX_Error pointer upon failure.
+ *
+ * Unless otherwise noted, for all accessor (gettor) functions that return a
+ * PKIX_PL_Object pointer, callers should assume that this pointer refers to a
+ * shared object. Therefore, the caller should treat this shared object as
+ * read-only and should not modify this shared object. When done using the
+ * shared object, the caller should release the reference to the object by
+ * using the PKIX_PL_Object_DecRef function.
+ *
+ * While a function is executing, if its arguments (or anything referred to by
+ * its arguments) are modified, free'd, or destroyed, the function's behavior
+ * is undefined.
+ *

+
+/* PKIX_CertSelector
+ *
+ * PKIX_CertSelectors provide a standard way for the caller to select
+ * certificates based on particular criteria. A CertSelector is typically used
+ * by the caller to specify the constraints they wish to impose on the target
+ * certificate in a chain. (see pkix_params.h) A CertSelector is also often
+ * used to retrieve certificates from a CertStore that match the selector's
+ * criteria. (See pkix_certstore.h) For example, the caller may wish to only
+ * select those certificates that have a particular Subject Distinguished Name
+ * and a particular value for a private certificate extension. The
+ * MatchCallback allows the caller to specify the custom matching logic to be
+ * used by a CertSelector.
+ *
+ * By default, the MatchCallback is set to point to the default implementation
+ * provided by libpkix, which understands how to process the most common
+ * parameters. If the default implementation is used, the caller should set
+ * these common parameters using PKIX_CertSelector_SetCommonCertSelectorParams.
+ * Any common parameter that is not set is assumed to be disabled, which means
+ * the default MatchCallback implementation will select all certificates
+ * without regard to that particular disabled parameter. For example, if the
+ * SerialNumber parameter is not set, MatchCallback will not filter out any
+ * certificate based on its serial number. As such, if no parameters are set,
+ * all are disabled and any certificate will match. If a parameter is
+ * disabled, its associated PKIX_ComCertSelParams_Get* function returns a
+ * default value of NULL, or -1 for PKIX_ComCertSelParams_GetBasicConstraints
+ * and PKIX_ComCertSelParams_GetVersion, or 0 for
+ * PKIX_ComCertSelParams_GetKeyUsage.
+ *
+ * If a custom implementation is desired, the default implementation can be
+ * overridden by calling PKIX_CertSelector_SetMatchCallback. In this case, the
+ * CertSelector can be initialized with a certSelectorContext, which is where
+ * the caller can specify the desired parameters the caller wishes to match
+ * against. Note that this certSelectorContext must be an Object (although any
+ * object type), allowing it to be reference-counted and allowing it to
+ * provide the standard Object functions (Equals, Hashcode, ToString, Compare,
+ * Duplicate).
