Hi, I needed a lot coffee and tobacco resources to find out that rt_task_spawn with NULL name will not work in userspace. The call failed with -3 (ESRCH?). This error seems not documented the xenomai api documention.
Using rt_task_create and rt_task_start it was rt_task_start that failed. I think this is related to Jans statement below. As rt_task_spawn is a inline function and a combination of create/start, this can be confusing. I.e. rt_task_shadow works with NULL name and rt_task_spawn dont. At this point I should mention that im testing my pascal-translations of the xenomai native and rtdm headers, but i dont see that the problem should be related to it, I searched the problem a long time i this part ;-) Some questions: Im still using Xenomai 2.0.1, is this the problem ? Shouldnt this be documented better ? Would it work if rt_task_spawn is a skincall? pascal-related: Is there a way to export the c-inline functions also in the libs, so that the complete api is exported ? rt_task_spawn and some rt_*_unbind funtions are inlined. Its not a problem to reprogram these in pascal, but for maintenance reasons it would be nice if i could link against these functions. greetings kisda Am Donnerstag, 8.
