Function close [src]

Closes the file descriptor. Asserts the file descriptor is open. This function is not capable of returning any indication of failure. An application which wants to ensure writes have succeeded before closing must call fsync before close. The Zig standard library does not support POSIX thread cancellation.

Prototype

pub fn close(fd: fd_t) void

Parameters

fd: fd_t

Source

  pub fn close(fd: fd_t) void {
    if (native_os == .windows) {
        return windows.CloseHandle(fd);
    }
    if (native_os == .wasi and !builtin.link_libc) {
        _ = std.os.wasi.fd_close(fd);
        return;
    }
    switch (errno(system.close(fd))) {
        .BADF => unreachable, // Always a race condition.
        .INTR => return, // This is still a success. See https://github.com/ziglang/zig/issues/2425
        else => return,
    }
}
