Hi,

I wanted to know if it is advisible to call SysLink_setup multiple times from the same process context, with out calling SysLink_destroy. To elaborate, do you see an issue with calling syslink APIs in the following order from the same process context.

SysLink_setup

<<SYSLINK USAGE>>

SysLink_destroy

SysLink_setup() must be called by each process. The docs don't say whether you can call it multiple times from the same process (and I don't think we test that), so it's currently unclear whether that's supported.

A quick peek at the code looks like the underlying modules _are_ reference counted. So while I wouldn't say it's "advisable", it probably is safe to do. But most users don't do that, so at best it's a poorly tested feature.

Is there a reason you want to do this?

Thanks Chris.

The reason of asking this question is that i need to do syslink operations before calling OMX_init from the SDK package.

I know SysLink_setup is getting called inside OMX_init and hence the question.

Sounds reasonable. Please give it a try, and if you have issues, start a new thread and we can help out.

A quick [unfortunate] followup, we gave this a quick try (setup, setup, destroy, destroy) and we found errors during the 2nd destroy. So as of now, the latest release of SysLink 2.x (currently 2.10.00.12) and earlier do _not_ allow multiple setup/destroy calls. You'll have to call SysLink_setup() once at the beginning and SysLink_destroy() once at the end.

I agree we _should_ support that use case, and we're looking into adding this support in a future release.
