Functions§

  • abort⚠
    cause abnormal termination
  • accept⚠
  • alloc⚠
  • alloc_zeroed⚠
  • available_parallelism⚠
    Returns an estimate of the default amount of parallelism a program should use. This number often corresponds to the amount of CPUs a computer has, but it may diverge in various cases.
  • 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⚠
  • dealloc⚠
  • dup⚠
    duplicate an existing file descriptor
  • errno⚠
    Get the last error number from the thread local storage
  • 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 status to the host system
  • fcntl⚠
  • free⚠
  • 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⚠Deprecated
    determines the number of activated processors
  • getaddrbyname⚠
    The system call getaddrbyname determine the network host entry. It expects an array of u8 with a size of in_addr or of in6_addr. The result of the DNS request will be stored in this array.
  • 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
  • nanosleep⚠
    suspend thread execution for an interval measured in nanoseconds
  • network_init⚠
    initialize the network stack
  • notify⚠
  • open⚠
    open and possibly create a file
  • opendir⚠Deprecated
    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.
  • readv⚠
    read() attempts to read nbyte of data to the object referenced by the descriptor fd from a buffer. read() performs the same action, but scatters the input data from the iovcnt buffers specified by the members of the iov array: iov[0], iov[1], ..., iov[iovcnt-1].
  • realloc⚠
  • 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. If pshared is nonzero, then the semaphore is shared between processes (currently not supported).
  • 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⚠
    shut down part of a full-duplex connection
  • shutdown_socket⚠Deprecated
  • 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
  • writev⚠
    write() attempts to write nbyte of data to the object referenced by the descriptor fd from a buffer. writev() performs the same action, but gathers the output data from the iovcnt buffers specified by the members of the iov array: iov[0], iov[1], ..., iov[iovcnt-1].
  • yield_now⚠
    yield the processor
