/* TODO list:
*
* - php.ini flags
* especialliy important for things like oci_ping
* - Change return-value for OCIFetch*() (1-row read, 0-Normal end, false-error)
* - Error mode (print or shut up?)
* - OCIPasswordChange()
* - binding of arrays
* - Character sets for NCLOBS
* - split the module into an upper (php-callable) and lower (c-callable) layer!
* - remove all XXXs
* - clean up and documentation
* - make OCIInternalDebug accept a mask of flags....
* - add some flags to OCIFetchStatement (maxrows etc...)
* - have one ocifree() call.
* - make it possible to have persistent statements?
* - implement connection pooling in ZTS mode.
* - implement automatic commit *OR* rollback on script end
* - failover
* - change all the lob stuff to work without classes (optional)!
* - make sure that the callbacks terminate the strings with \0
* - cleanup the ociexecute semantics for refcursors
* - make $lob->savefile use O_BINARY
* - line 2728: ub4 length = -1; needs fixing
* - delay OCIInitialize() as far as we can.
* - add PHP Array <-> OCICollection conversion
* - add Collection iterator object for INDEX BY tables
