--------------------------------OCIAttrGet------------------------------------

OCIAttrGet()
Name
OCI Attribute Get
Purpose
This call is used to get a particular attribute of a handle. 
Syntax
sword OCIAttrGet ( CONST dvoid    *trgthndlp,
                 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. 
attributep (OUT) - is a pointer to the storage for an attribute value. The 
attribute value is filled in. 
sizep (OUT) - is the size of the attribute value. 
This can be passed in as NULL for most parameters as the size is well known. 
For text* parameters, a pointer to a ub4 must be passed in to get the length 
of the string. 
attrtype (IN) - is the type of attribute.
errhp (IN/OUT) - an error handle which can be passed to OCIErrorGet() for 
diagnostic information in the event of an error.

OCIAttrSet()

--------------------------------OCIAttrSet------------------------------------


OCIAttrSet()
Name
OCI Attribute Set
Purpose
This call is used to set a particular attribute of a handle or a descriptor. 
Syntax
sword OCIAttrSet ( dvoid       *trgthndlp,
                 ub4         trghndltyp,
                 dvoid       *attributep,
                 ub4         size,
                 ub4         attrtype,
                 OCIError    *errhp );
Comments
This call is used to set a particular attribute of a handle or a descriptor. 
See Appendix B for a list of handle types and their writeable attributes.
Parameters
trghndlp (IN/OUT) - the pointer to a handle type whose attribute gets 
modified. 
trghndltyp (IN/OUT) - is the handle type. 
attributep (IN) - a pointer to an attribute value. 
The attribute value is copied into the target handle. If the attribute value 
is a pointer, then only the pointer is copied, not the contents of the pointer.
size (IN) - is the size of an attribute value. This can be passed in as 0 for 
most attributes as the size is already known by the OCI library. For text*
attributes, a ub4 must be passed in set to the length of the string. 
attrtype (IN) - the type of attribute being set.
errhp (IN/OUT) - an error handle which can be passed to OCIErrorGet() for 
diagnostic information in the event of an error.
