                             unsigned short   resultLen,
                             unsigned short  *requiredLen,
                             unsigned long   *searchHandle,
                             cwbSV_ErrHandle  errorHandle);

Parameters

char * resultPtr - output

Pointer to the buffer to contain the result.
