[for]OCI development

text * colname;//The field name
OCIAttrGet(...,(dvoid *)&colname,....);//To obtain the field name

The above two code taken from the official OCI development example, I really don't know), OCIAttrGet (third parameter attributep is obviously a dvoid * type, but the function to obtain the field name, why the input argument colname will be preceded by a"&"?

Beg the answer~~~
