> There is some semantic confusion about what the process ID represents in NuttX. NuttX uses a "task group" to associate all of the heavyweight threads. The process ID means two things. It it the thread ID of the main thread of task group (maintained in the TCB) but it is also the task group ID of the entire collection of associated threads (maintained in the group structure, usually). > > group ID is overloaded. Sorry about that. NuttX does not support group security as does Linux. The group ID refers to the "task group", not to the security group. With https://github.com/apache/incubator-nuttx/pull/2981, group ID doesn't exist anymore, the task is represented by the main thread proccess ID now. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
