This section lists each function argument, along with its data type, a description and whether it is an input or output argument.
Only SQLGetInfo() and SQLBindParameter() have parameters that are both input and output.
Some functions contain input or output arguments which are known as deferred or bound arguments.
These arguments are pointers to buffers allocated by the application, and are associated with (or bound to) either a parameter in an SQL statement, or a column in a result set. The data areas specified by the function are accessed by DB2 CLI at a later time. It is important that these deferred data areas are still valid at the time DB2 CLI accesses them.
