C++ (Cpp) workfile_mgr_create_fileno Examples

Example #1

File: workfile_file.c Project: a320321wb/incubator-hawq

/*
 * Creates a new workfile in a given set
 *
 *  The next file name in the sequence is generated
 */

	Assert(NULL != work_set);

	work_set->no_files++;

}

Example #2

 * Save the serialized plan to a file in the workfile set.
 * It will be used to do full plan matching before reusing.
 */
