Author: Frank Warmerdam
Contact: warmerdam@…
Status: Development

Summary

In an effort to better support thread safety in OGR some methods are added as internal infrastructure is updated.

Definitions

Reentrant: A reentrant function can be called simultaneously by multiple threads provided that each invocation of the function references unique data.

Thread-safe: A thread-safe function can be called simultaneously by multiple threads when each invocation references shared data. All access to the shared data is serialized.
