Function Documentation

unsigned int CDM_countInstance (  unsigned short  schema  )

Count instances of a CDM database with a given schema. Parameters: schema  (in) Database schema Return values: x  Number of instances Count the number of database instances with the given schema.

CMX_asBuiltIdentity* CDM_findCAB (  CDM_Database *  cdb  )

Return the link to the CMX as built identity block. Parameters: cdb  (in) CDM database handle Return values: x  CMX as built identity block pointer 0  Cannot find the CMX as built identity block

CDM_Database * CDM_findDatabase (  unsigned short  schema, unsigned short  instance )

Find a CDM database by schema and instance. Parameters: schema  (in) Database schema instance  (in) Database instance number Return values: x  Handle for database NULL  Database not found Find a CDM database by schema and instance.

const void * CDM_getData (  CDM_Database *  cdb  )

Return a pointer to the data block of a CDM database instance. Parameters: cdb  (in) CDM database handle Return values: x  Pointer to database data block NULL  Invalid database handle

short CDM_getInstance (  CDM_Database *  cdb  )

Return the instance number of a CDM database instance. Parameters: cdb  (in) CDM database handle Return values: x  Instance number CDM_K_NONE  Invalid database handle

unsigned int CDM_getKey (  CDM_Database *  cdb  )

Return the file key of a CDM database instance. Parameters: cdb  (in) CDM database handle Return values: x  File key 0  File key not found

short CDM_getSchema (  CDM_Database *  cdb  )

Return the schema number of a CDM database instance. Parameters: cdb  (in) CDM database handle Return values: x  Database schema number CDM_K_NONE  Invalid database handle

short CDM_getVersion (  CDM_Database *  cdb  )

Return the version of a CDM database instance. Parameters: cdb  (in) CDM database handle Return values: x  Database version CDM_K_NONE  Invalid database handle

void CDM_insertDatabase (  CDM_Database *  new  )

Insert a CDM database into the database list. Parameters: new  (in) CDM database handle Insert a CDM database instance into the database list.

void CDM_removeDatabase (  CDM_Database *  old  )

Remove a CDM database from the database list. Parameters: old  (in) CDM database handle Remove a CDM database instance from the database list.

unsigned int CDM_scanDatabase (  CDM_cb_ScanDatabase *  rtn, void *  prm )

Scan though the database instance list. Parameters: rtn  (in) Scan callback routine prm  (in) Scan callback routine parameter Return values: x  Return code from last scan call made. CDM_scanDatabase() scans through the CDM database instance list, calling the provided callback routine for each member. The scan is aborted if the callback routine returns a failure code (least significant bit set).
