Shared CGO Packages

The pkg/ directory houses low-level building blocks that require CGO and are shared by multiple protocols/modules.

Current packages:

Package	Description
dbdriver/	Thin wrappers around IBM’s DB2 CLI driver (dynamic loading, environment setup).
odbcbridge/	Lightweight bridge that exposes ODBC handles to Go code with safe conversions.
odbcwrapper/	Higher-level helpers for executing queries and scanning results through the bridge.

These packages are intentionally small and focus on ABI boundaries. Business logic belongs in protocols/ and modules/.

When touching CGO code remember to:

• Keep build tags accurate (//go:build cgo).
• Free allocated C resources even on error paths.
• Document any required compile-time flags or environment variables.
