//
// sys_arch_thread.h
//
// Contains definition of the sys_arch_thread struct which the VDK porting
// layer uses to describe each thread that lwIP creates.
//
// Member 'timeouts' is void* rather than struct timeouts to avoid importing
// lwIP include files into lwIP_ThreadType.[ch].
//
// The lwIP_ThreadType ErrorFunction() sets the 'error_cause' and 'error_value'
// members before returning control to the point just after the failing
// VDK API call. That's how timed-out semaphores are detected.
//
// Note that lwIP_ThreadType's Destroy() function sets the 'id' member to 
// UINT_MAX just before it exits to mark the structure as free.
