DESCRIPTION
-----------------------------OCIXmlDbInitXmlCtx---------------------------------
Name
OCIXmlDbInitXmlCtx
Purpose
To get a xmlctx structure initialized with error-handler and XDB callbacks.
Syntax
struct xmlctx *OCIXmlDbInitXmlCtx (OCIEnv *envhp,
OCISvcCtx *svchp,
OCIError *err,
params_ocixmldb *params,
int num_params);
Parameters
envhp (IN) - The OCI environment handle
svchp (IN) - The OCI service handle
errhp (IN) - The OCI error handle
params (IN)- This contains the following optional parameters :
(a) OCIDuration dur (IN - The OCI Duration (Default: OCI_DURATION_SESSION)
(b) void (*err_handler) (sword, (const oratext *) (IN) -
Pointer to the error handling function (Default: null)
num_params (IN) - Number of parameters to be read from parameter params.
If the value of num_params exceeds the size of array
"params", unexpected behavior will result.
Returns
A pointer to xmlctx structure, with xdb context, error handler and callbacks
populated with appropriate values. This is later used for all API calls. NULL
if no database connection available.
-----------------------------OCIXmlDbFreeXmlCtx----------------------------
Name
OCIXmlDbFreeXmlCtx
Pupose
To free any allocations done during OCIXmlDbInitXmlCtx.
Syntax
void OCIXmlDbFreeXmlCtx (struct xmlctx *xctx)
Parameters
xctx (IN) - The xmlctx to terminate
Returns
-
------------------------OCIXmlDbOrastreamFromLob---------------------------
Name
OCIXmlDbOrastreamFromLob
Pupose
To create an orastream from a lob. This orastream can be used by functions like XMLLoadDom().
Syntax
sword OCIXmlDbOrastreamFromLob(OCIError *errhp, xmlctx *xctx,
void **stream, OCILobLocator *lobloc)
Parameters
envhp (IN) - The OCI environment handle
xctx (IN) - XML context
stream (IN/OUT) - A pointer to orastream
lobloc (IN) - The OCI lob locator
Returns
The orastream created on top of the lob is returned in the parameter 'stream'.
