- *  Creates a new TargetCertCheckerState using the CertSelector pointed to

- *
- * PARAMETERS:

- *  "certsRemaining"
- *      Number of certificates remaining in the chain.
- *  "pState"
- *      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 TargetCertCheckerState Error if the function fails in a
- *      non-fatal way.
- *  Returns a Fatal Error if the function fails in an unrecoverable way.

- * FUNCTION: pkix_TargetCertChecker_Initialize
- * DESCRIPTION:
- *
- *  Creates a new CertChainChecker and stores it at "pChecker", where it will
- *  used by pkix_TargetCertChecker_Check to check that the final certificate
- *  of a chain meets the criteria of the CertSelector pointed to by
- *  "certSelector". The number of certs remaining in the chain, represented by
- *  "certsRemaining" is used to initialize the checker's state.
- *
- * PARAMETERS:
- *  "certSelector"
- *      Address of CertSelector representing the criteria against which the
- *      final certificate in a chain is to be matched. May be NULL.
- *  "certsRemaining"
- *      Number of certificates remaining in the chain.
- *  "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.
