       crtest - test cases for QDBM Curia


       crtest write [-s] [-lob] name rnum bnum dnum
       crtest read [-wb] [-lob] name
       crtest rcat [-c] name rnum bnum dnum pnum align
       crtest combo name
       crtest wicked [-c] name rnum


       The  command  ‘crtest’  is  a utility for facility test and performance
       test.  Check a  database  generated  by  the  command  or  measure  the
       execution  time  of the command.  This command is used in the following
       format.  ‘name’ specifies a database name.  ‘rnum’ specifies the number
       of records.  ‘bnum’ specifies the number of elements of a bucket array.
       ‘dnum’  specifies  the  number  of  division  of  a  database.   ‘pnum’
       specifies  the  number  of patterns of the keys.  ‘align’ specifies the
       basic size of alignment.  ‘fbpsiz’ specifies the size of the free block

       crtest write [-s] [-lob] name rnum bnum dnum
              Store  records with keys of 8 bytes.  They change as ‘00000001’,

       crtest read [-wb] [-lob] name
              Retrieve all records of the database above.

       crtest rcat [-c] name rnum bnum dnum pnum align fbpsiz
              Store records with partway  duplicated  keys  using  concatenate

       crtest combo name
              Perform combination test of various operations.

       crtest wicked [-c] name rnum
              Perform updating operations selected at random.

       Options feature the following.

              -s : make the files sparse.
              -lob : handle large objects.
              -wb  :  use  the  function  ‘crgetwb’  instead  of  the function
              -c : perform comparison test with map of Cabin.

       This command returns 0 on success, another on failure.  The environment
       variable  ‘QDBMDBGFD’  specifies  the  file  descriptor  to  output the
       history of updating the variable ‘dpecode’.
