This function creates a new database. This functions is obsolete. Applications instead should call CeCreateDatabaseEx.
A remote application interface (RAPI) version of this function exists, and it is also named CeCreateDatabase.

Syntax
CEOID CeCreateDatabase(LPWSTR lpszName, DWORD dwDbaseType, WORD wNumSortOrder, SORTORDERSPEC * rgSortSpecs);
Parameters
lpszName
[in] Long pointer to a null-terminated string that specifies the name for the new database. The name can have up to 32 characters, including the terminating null character. If the name is too long, it is truncated and the database is created. Do not use an empty string as the database name.
dwDbaseType
[in] Specifies the type identifier for the database. This is an application-defined value that can be used for any application-defined purpose. For example, an application can use the type identifier to distinguish address book data from to-do list data or use the identifier during a database enumeration sequence. See CeFindFirstDatabase for details. The type identifier is not meant to be a unique identifier for the database. The system does not use this value.
wNumSortOrder
[in] Number of sort orders active in the database, with four being the maximum number. This parameter can be zero if no sort orders are active. If this value is zero, then the database engine creates a default sort order where "rgSortSpecs[0].propid = 0", and "rgSortSpecs[0].dwFlags = CEDB_SORT_GENERICORDER." This is only a placeholder and does not influence the insertion order of the records.
rgSortSpecs
[in] Pointer to an array of actual sort order descriptions. The size of the array is specified by wNumSortOrder. This parameter can be NULL if wNumSortOrder is zero.
Return Values
The object identifier of the newly created database—not a handle to an open database—indicates success. NULL indicates failure. To get extended error information within a Windows CE program, call GetLastError. Possible values for GetLastError include the following:
ERROR_DISK_FULL
The object store does not contain enough space to create the new database.
ERROR_INVALID_PARAMETER
A parameter was invalid.
ERROR_DUP_NAME
A database already exists with the specified name.
Remarks
Because sort orders increase the system resources needed to perform each insert and delete operation, keep the number of sort orders to a minimum. However, try not to specify too few sort orders. If you do, you can use the CeSetDatabaseInfoEx function to change the sort order later; however, this function is even more expensive in terms of system resources.
