31 * (Errnos are host errnos; we rely on QEMU_ERESTARTSYS not clashing
32 * with any of the host errno values.)
68 * Here it is important that the host syscall is made
69 * via this safe_syscall() function, and *not* via the host libc.
70 * If the host libc is used then the implementation will appear to work
72 * signal could arrive just before we make the host syscall inside libc,
79 * (If the implementation needs to make multiple host syscalls this is
82 * stay in the host kernel indefinitely) it's OK to use libc if necessary.
92 * The basic setup is that we make the host syscall via a known
93 * section of host native assembly. If a signal occurs, our signal
94 * handler checks the interrupted host PC against the address of that
104 * (1) signal came in just before we took the host syscall (a race);
109 * (2) signal came in while the host syscall was blocking, and the
110 * host kernel decided the syscall should be restarted;
115 * host syscall was blocking, and the host kernel decided that the syscall
116 * should not be restarted; in this case QEMU's host signal handler will
