mcTBcreateDesc creates a descriptor table in memory (not on the database, to create a relational table on the database make use of mcDBresSet or mcDBresSuperset). mcTBcreateDesc performs the same function as mcTBcreate, except that the table size is defined by the current default descriptor size, the default descriptor size being 1024 bytes). To modify the default descriptor size, make use of the mcTBsetDescSize.

If successful, the function returns a pointer to a new table in memory (not on database). Otherwise, NULL is returned and the error code can be retrieved by the function mcErrStatus.
