35 #include <sys/ucontext.h>
37 * The file sys/regset.h defines indices in the gregset_t array,
38 * such as EIP on i386. Those defines were historically exposed
39 * via sys/ucontext.h, sys/signal.h, etc. which caused surprises
40 * due to those defines unexpectedly polluting the namespace.
41 * On the other hand, several existing applications assume that
42 * the regset names are defined after an include <ucontext.h>.
43 * To solve both problems at once: <ucontext.h> (this file)
44 * DOES include sys/regset.h for you but <sys/ucontext.h>
45 * does NOT include sys/regset.h anymore.
