pro*c is thread safe on various platforms but mostly starting with 2.3 and up of pro*c (the pro*c that comes with 7.3).
If your pro*c manual does not have a section "Developing Multi–threaded Applications" in chapter 3 "Developing Pro C/C++ Applications" you probably don't have support for it. (even if you do have those chapters, you need to refer to your OS documentation to see if its supported on that platform)....
If you do have those chapters -- are you using the EXEC SQL CONTEXT and related statements?
