OCIAttrGet()
Name
OCI Attribute Get
Purpose
This call is used to get a particular attribute of a handle.

                 ub4            trghndltyp,
                 dvoid          *attributep,
                 ub4            *sizep,
                 ub4            attrtype,
                 OCIError       *errhp );
Comments
This call is used to get a particular attribute of a handle.
See Appendix B,  "Handle Attributes",  for a list of handle types and their 
readable attributes.
Parameters
trgthndlp (IN) - is the pointer to a handle type. 
trghndltyp (IN) - is the handle type.
