    fd_pread ¶

    fd_pread :: proc "contextless" (
    	fd:     fd_t, 
    	iovs:   [][]u8, 
    	offset: filesize_t, 
    ) -> (n: uint, err: errno_t) {…}
     

    Read from a file descriptor, without using and updating the file descriptor's offset. Note: This is similar to preadv in POSIX. @return The number of bytes read.

    fd_pwrite ¶

    fd_pwrite :: proc "contextless" (
    	fd:     fd_t, 
    	iovs:   [][]u8, 
    	offset: filesize_t, 
    ) -> (n: uint, err: errno_t) {…}

    fd_read ¶

    fd_read :: proc "contextless" (fd: fd_t, iovs: [][]u8) -> (n: uint, err: errno_t) {…}
     

    Read from a file descriptor. Note: This is similar to readv in POSIX. @return The number of bytes read.

    fd_readdir ¶

    fd_readdir :: proc "contextless" (
    	fd:     fd_t, 
    	buf:    []u8, 
    	cookie: dircookie_t, 
    ) -> (n: uint, err: errno_t) {…}
     

    Read directory entries from a directory. When successful, the contents of the output buffer consist of a sequence of directory entries. Each directory entry consists of a dirent object, followed by dirent::d_namlen bytes holding the name of the directory entry. This function fills the output buffer as much as possible, potentially truncating the last directory entry. This allows the caller to grow its read buffer size in case it's too small to fit a single large directory entry, or skip the oversized directory entry. @return The number of bytes stored in the read buffer. If less than the size of the read buffer, the end of the directory has been reached.

    fd_renumber ¶

    fd_renumber :: proc "contextless" (fd: fd_t, to: fd_t) -> errno_t ---
     

    Atomically replace a file descriptor by renumbering another file descriptor. Due to the strong focus on thread safety, this environment does not provide a mechanism to duplicate or renumber a file descriptor to an arbitrary number, like dup2(). This would be prone to race conditions, as an actual file descriptor with the same number could be allocated by a different thread at the same time. This function provides a way to atomically renumber file descriptors, which would disappear if dup2() were to be removed entirely.

    fd_seek ¶

    fd_seek :: proc "contextless" (
    	fd:     fd_t, 
    	offset: filedelta_t, 
    	whence: whence_t, 
    ) -> (new_offset: filesize_t, err: errno_t) {…}
     

    Move the offset of a file descriptor. Note: This is similar to lseek in POSIX. @return The new offset of the file descriptor, relative to the start of the file.

    fd_sync ¶

    fd_sync :: proc "contextless" (f: fd_t) -> errno_t ---
     

    Synchronize the data and metadata of a file to disk. Note: This is similar to fsync in POSIX.

    fd_tell ¶

    fd_tell :: proc "contextless" (fd: fd_t) -> (offset: filesize_t, err: errno_t) {…}
     

    Return the current offset of a file descriptor. Note: This is similar to lseek(fd, 0, SEEK_CUR) in POSIX. @return The current offset of the file descriptor, relative to the start of the file.

    fd_write ¶

    fd_write :: proc "contextless" (fd: fd_t, iovs: [][]u8) -> (n: uint, err: errno_t) {…}
     

    Write to a file descriptor. Note: This is similar to writev in POSIX.

    path_create_directory ¶

    path_create_directory :: proc "contextless" (fd: fd_t, path: string) -> errno_t ---
     

    Create a directory. Note: This is similar to mkdirat in POSIX.

    	path:  string, 
    ) -> (offset: filestat_t, err: errno_t) {…}
     

    Return the attributes of a file or directory. Note: This is similar to stat in POSIX. @return The buffer where the file's attributes are stored.

    path_filestat_set_times ¶

    path_filestat_set_times :: proc "contextless" (
    	fd:        fd_t, 
    	flags:     lookupflags_t, 
    	path:      string, 
    	atim:      timestamp_t, 
    	mtim:      timestamp_t, 
    	fst_flags: fstflags_t, 
    ) -> errno_t ---
     

    Adjust the timestamps of a file or directory. Note: This is similar to utimensat in POSIX.

    path_link :: proc "contextless" (
    	old_fd:    fd_t, 
    	old_flags: lookupflags_t, 
    	old_path:  string, 
    	new_fd:    fd_t, 
    	new_path:  string, 
    ) -> errno_t ---
     

    Create a hard link. Note: This is similar to linkat in POSIX.

    path_open ¶

    path_open :: proc "contextless" (
    	fd:                   fd_t, 
    	dirflags:             lookupflags_t, 
    	path:                 string, 
    	oflags:               oflags_t, 
    	fs_rights_base:       rights_t, 
    	fs_rights_inheriting: rights_t, 
    	fdflags:              fdflags_t, 
    ) -> (file: fd_t, err: errno_t) {…}
     

    Open a file or directory. The returned file descriptor is not guaranteed to be the lowest-numbered file descriptor not currently open; it is randomized to prevent applications from depending on making assumptions about indexes, since this is error-prone in multi-threaded contexts. The returned file descriptor is guaranteed to be less than 2**31. Note: This is similar to openat in POSIX. @return The file descriptor of the file that has been opened.

    path_readlink :: proc "contextless" (
    	fd:   fd_t, 
    	path: string, 
    	buf:  []u8, 
    ) -> (n: uint, err: errno_t) {…}
     

    Read the contents of a symbolic link. Note: This is similar to readlinkat in POSIX. @return The number of bytes placed in the buffer.

    path_remove_directory ¶

    path_remove_directory :: proc "contextless" (fd: fd_t, path: string) -> errno_t ---

    	fd:       fd_t, 
    	old_path: string, 
    	new_fd:   fd_t, 
    	new_path: string, 
    ) -> errno_t ---
     

    Rename a file or directory. Note: This is similar to renameat in POSIX.

    path_symlink :: proc "contextless" (old_path: string, fd: fd_t, new_path: string) -> errno_t ---
     

    Create a symbolic link. Note: This is similar to symlinkat in POSIX.

    path_unlink_file :: proc "contextless" (fd: fd_t, path: string) -> errno_t ---
     

    Unlink a file. Return errno::isdir if the path refers to a directory. Note: This is similar to unlinkat(fd, path, 0) in POSIX.

    poll_oneoff ¶

    poll_oneoff :: proc "contextless" (
    	subscription_in: ^subscription_t, 
    	event_out:       ^event_t, 
    	nsubscriptions:  uint, 
    ) -> (n: uint, err: errno_t) {…}
     

    Concurrently poll for the occurrence of a set of events. @return The number of events stored.

    proc_exit ¶

    proc_exit :: proc "contextless" (rval: exitcode_t) -> ! ---
     

    Terminate the process normally. An exit code of 0 indicates successful termination of the program. The meanings of other values is dependent on the environment.

    proc_raise ¶

    proc_raise :: proc "contextless" (sig: signal_t) -> errno_t ---
     

    Send a signal to the process of the calling thread. Note: This is similar to raise in POSIX.

    random_get ¶

    random_get :: proc "contextless" (buf: []u8) -> errno_t ---
     

    Write high-quality random data into a buffer. This function blocks when the implementation is unable to immediately provide sufficient high-quality random data. This function may execute slowly, so when large mounts of random data are required, it's advisable to use this function to seed a pseudo-random number generator, rather than to provide the random data directly.

    sched_yield ¶

    sched_yield :: proc "contextless" () -> errno_t ---
     

    Temporarily yield execution of the calling thread. Note: This is similar to sched_yield in POSIX.

    sock_recv ¶

    sock_recv :: proc "contextless" (
    	fd:       fd_t, 
    	ri_data:  [][]u8, 
    	ri_flags: riflags_t, 
    ) -> (n: uint, flags: roflags_t, err: errno_t) {…}
     

    Receive a message from a socket. Note: This is similar to recv in POSIX, though it also supports reading the data into multiple buffers in the manner of readv. @return Number of bytes stored in ri_data and message flags.

    sock_send ¶

    sock_send :: proc "contextless" (
    	fd:       fd_t, 
    	si_data:  [][]u8, 
    	si_flags: siflags_t, 
    ) -> (n: uint, err: errno_t) {…}
     

    Send a message on a socket. Note: This is similar to send in POSIX, though it also supports writing the data from multiple buffers in the manner of writev. @return Number of bytes transmitted.

    sock_shutdown ¶

    sock_shutdown :: proc "contextless" (fd: fd_t, how: sdflags_t) -> errno_t ---
     

    Shut down socket send and receive channels. Note: This is similar to shutdown in POSIX.
