constraint type

Oracle V6.0 has two tables for constraint: constraint_defs and constraint_columns.

 desc constraint_defs

 Name                            Null?    Type
 ------------------------------- -------- ----
 OWNER                           NOT NULL CHAR(30)
 CONSTRAINT_NAME                 NOT NULL CHAR(30)
 CONSTRAINT_TYPE                          CHAR(1)    <<
 TABLE_NAME                      NOT NULL CHAR(30)
 SEARCH_CONDITION                         LONG
 R_OWNER                         NOT NULL CHAR(30)
 R_CONSTRAINT_NAME               NOT NULL CHAR(30)

how many types are defined for CONSTRAINT_TYPE?

I found that at least two types P and C. However, there is no explanation written in the DBA Guide.

Does anyone know what these mean?
