Internal native CPU API | |
| typedef void(* | _native_callback_t) (void) |
| Prototype for native's internal callbacks. | |
| void | native_cpu_init (void) |
| Initializes native CPU. | |
Native Signal Handling | |
| void | native_interrupt_init (void) |
| Registers signal handlers for the native CPU. | |
| int | native_register_interrupt (int sig, _native_callback_t handler) |
| Register interrupt handler handler for interrupt signal. More... | |
| int | native_unregister_interrupt (int sig) |
| Unregister interrupt handler for interrupt signal. More... | |
| void | _native_sig_leave_tramp (void) |
| Switches to ISR context, then enables IRQ and returns to userspace. More... | |
System Calls | |
We wrap system calls and syscall-invoking library calls to ensure no context switches occur during a system call. | |
| static void | _native_pending_syscalls_up (void) |
| Increment spending system call counter. | |
| static void | _native_pending_syscalls_down (void) |
| Decrements pending system call counter. | |
| void | _native_init_syscalls (void) |
| Registers system calls. More... | |
Native Context Switching | |
| volatile uintptr_t | _native_user_fptr |
| Points to instruction in userspace where RIOT left off and switched to ISR context. | |
| volatile int | _native_in_isr |
| A boolean variable indicating whether program execution currently takes place in an ISR context. | |
| char | _isr_stack [THREAD_STACKSIZE_DEFAULT] |
| Stack used in ISR context. | |
| ucontext_t * | _native_isr_context |
| ISR context. | |
| static void | _native_isr_context_make (void(*func)(void)) |
Makes ISR context so that execution continues at func when the context is applied. More... | |
| static ucontext_t * | _native_user_context (void) |
| Retrieves user context. More... | |
Native Read/Write Methods | |
| ssize_t | _native_read (int fd, void *buf, size_t count) |
| Reads file, populates given buffer. | |
| ssize_t | _native_write (int fd, const void *buf, size_t count) |
| Writes given data into file. | |
| ssize_t | _native_writev (int fildes, const struct iovec *iov, int iovcnt) |
| Performs a vectored write operation. | |
