782 * FUNCTION: pkix_CRLSelector_Select
783 * DESCRIPTION:
784 *
785 * This function applies the selector pointed to by "selector" to each CRL,
786 * in turn, in the List pointed to by "before", and creates a List containing
787 * all the CRLs that matched, or passed the selection process, storing that
788 * List at "pAfter". If no CRLs match, an empty List is stored at "pAfter".
789 *
790 * The List returned in "pAfter" is immutable.
791 *
792 * PARAMETERS:
793 * "selector"
794 * Address of CRLSelelector to be applied to the List. Must be non-NULL.
795 * "before"
796 * Address of List that is to be filtered. Must be non-NULL.
797 * "pAfter"
798 * Address at which resulting List, possibly empty, is stored. Must be
799 * non-NULL.
800 * "plContext"
801 * Platform-specific context pointer.
802 * THREAD SAFETY:
803 * Thread Safe (see Thread Safety Definitions in Programmer's Guide)
804 * RETURNS:
805 * Returns NULL if the function succeeds.
806 * Returns a CRLSelector Error if the function fails in a non-fatal way.
807 * Returns a Fatal Error if the function fails in an unrecoverable way.
