Parameters
ctype
A templated parameter that is the data type.
nParam
[in] The parameter number (offset from 1). Parameter 0 is reserved for return values. The parameter number is the index of the parameter based on its order in the SQL or stored procedure call. See SetParam for an example.
pParamName
[in] The parameter name.
pData
[out] The pointer to the memory containing the data retrieved from the buffer.
Return Value
