Constants§

Functions§

  • abort⚠
    cause abnormal termination
  • accept⚠
  • bind⚠
    bind a name to a socket
  • block_current_task⚠
    Add current task to the queue of blocked tasks. After calling block_current_task, call yield_now to switch to another task.
  • block_current_task_with_timeout⚠
    Add current task to the queue of blocked tasks, but wake it when timeout milliseconds have elapsed.
  • clock_gettime⚠
    get current time
  • close⚠
    close a file descriptor
  • connect⚠
  • dup⚠
    duplicate an existing file descriptor
  • eventfd⚠
    eventfd creates an linux-like “eventfd object” that can be used as an event wait/notify mechanism by user-space applications, and by the kernel to notify user-space applications of events. The object contains an unsigned 64-bit integer counter that is maintained by the kernel. This counter is initialized with the value specified in the argument initval.
  • exit⚠
    cause normal termination and return arg to the host system
  • fcntl⚠
  • freeaddrinfo⚠
  • fstat⚠
    fstat
  • futex_wait⚠
    If the value at address matches the expected value, park the current thread until it is either woken up with futex_wake (returns 0) or an optional timeout elapses (returns -ETIMEDOUT).
  • futex_wake⚠
    Wake count threads waiting on the futex at address. Returns the number of threads woken up (saturates to i32::MAX). If count is i32::MAX, wake up all matching waiting threads. If count is negative or address is null, returns -EINVAL.
  • get_errno⚠
    Get the last error number from the thread local storage
  • get_priority⚠
    Determine the priority of the current thread
  • get_processor_count⚠
    determines the number of activated processors
  • getaddrinfo⚠
  • getdents64⚠
    getdents64 reads directory entries from the directory referenced by the file descriptor fd into the buffer pointed to by buf.
  • getpeername⚠
  • getpid⚠
    Determines the id of the current thread
  • getsockname⚠
  • getsockopt⚠
  • ioctl⚠
  • isatty
    returns true if file descriptor fd is a tty
  • join⚠
    join with a terminated thread
  • listen⚠
    listen for connections on a socket
  • lstat⚠
    lstat
  • malloc⚠
  • mkdir⚠
    ‘mkdir’ attempts to create a directory, it returns 0 on success and -1 on error
  • network_init⚠
    initialize the network stack
  • notify⚠
  • open⚠
    open and possibly create a file
  • opendir⚠
    open a directory
  • poll⚠
    The unix-like poll waits for one of a set of file descriptors to become ready to perform I/O. The set of file descriptors to be monitored is specified in the fds argument, which is an array of structures of pollfd.
  • read⚠
    read from a file descriptor
  • read_entropy⚠
    Fill len bytes in buf with cryptographically secure random data.
  • recv⚠
    receive() a message from a socket
  • recvfrom⚠
    receive() a message from a socket
  • rmdir⚠
    remove directory it refers to name
  • sem_destroy⚠
    sem_destroy() frees the unnamed semaphore at the address pointed to by sem.
  • sem_init⚠
    sem_init() initializes the unnamed semaphore at the address pointed to by sem. The value argument specifies the initial value for the semaphore.
  • sem_post⚠
    sem_post() increments the semaphore pointed to by sem. If the semaphore’s value consequently becomes greater than zero, then another thread blocked in a sem_wait call will be woken up and proceed to lock the semaphore.
  • sem_timedwait⚠
    decrement a semaphore
  • sem_trywait⚠
    try to decrement a semaphore
  • send⚠
  • sendto⚠
  • set_priority⚠
    Determine the priority of the current thread
  • setsockopt⚠
  • shutdown_socket⚠
    shut down part of a full-duplex connection
  • socket⚠
  • spawn⚠
    spawn a new thread
  • spawn2⚠
    spawn a new thread with user-specified stack size
  • stat⚠
    stat
  • unlink⚠
    delete the file it refers to name
  • usleep⚠
    suspend execution for microsecond intervals
  • wakeup_task⚠
    Wakeup task with the thread id tid
  • write⚠
    write to a file descriptor
  • yield_now⚠
    yield the processor
