- get current ucontext_t wht getcontext(); - allocate a stack with malloc(), add it to ucontext_t (uc_stack field) - call makecontext() to set the target function and argument - call swapcontext() swapcontext(3) uses setcontext(2), which setup the stack pointer according to what has been specified in ucontext_t. As far as I understand, setcontext(2) offers an MI interface and takes care of the MD problems, included those related to the stack. -- Emmanuel Dreyfus http://hcpnet.free.fr/pubz m...@netbsd.org
