- * FUNCTION: pkix_pl_CertBasicConstraints_Create
- * DESCRIPTION:
- *
- *  Creates a new CertBasicConstraints object whose CA Flag has the value
- *  given by the Boolean value of "isCA" and whose path length field has the
- *  value given by the "pathLen" argument and stores it at "pObject".
- *
- * PARAMETERS
- *  "isCA"
- *      Boolean value with the desired value of CA Flag.
- *  "pathLen"
- *      a PKIX_Int32 with the desired value of path length
- *  "pObject"
- *      Address of object pointer's destination. 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 CertBasicConstraints Error if the function fails
- *  in a non-fatal way.
- *  Returns a Fatal Error if the function fails in an unrecoverable way.
