thread_halt_self(9r) thread_halt_self(9r) NAME thread_halt_self - General: Handles asynchronous traps for self-termi‐ nating kernel threads SYNOPSIS void thread_halt_self( void ); ARGUMENTS None DESCRIPTION The thread_halt_self routine performs the work associated with a vari‐ ety of asynchronous traps (ASTs) for a kernel thread that terminates itself. A kernel thread terminates itself (or one kernel thread termi‐ nates another kernel thread) by calling the thread_terminate routine. The thread_halt_self routine examines the AST-related member of the thread structure pointer associated with the kernel thread that wants to terminate itself. This thread structure pointer was returned in a previous call to kernel_isrthread or kernel_thread_w_arg and passed by you to the thread_terminate routine. This AST-related member is set to a bit that identifies the specific AST trap associated with this kernel thread. Based on the AST bit set in this member, thread_halt_self does the appropriate cleanup work before the kernel thread exits from the kernel. NOTES A kernel thread that terminates itself must call thread_halt_self imme‐ diately after the call to thread_terminate. The reason for this is that thread_terminate only prepares the self-terminating kernel thread to stop execution. The thread_halt_self routine completes the work needed to stop execution of the self-terminating kernel thread by per‐ forming the appropriate cleanup work.
