</ul>     <h2 id="pkg-overview">Overview </h2> <p>Package syscall contains an interface to the low-level operating system primitives. The details vary depending on the underlying system, and by default, godoc will display the syscall documentation for the current system. If you want godoc to display syscall documentation for another system, set $GOOS and $GOARCH to the desired system. For example, if you want to view documentation for freebsd/arm on linux/amd64, set $GOOS to freebsd and $GOARCH to arm. The primary use of syscall is inside other packages that provide a more portable interface to the system, such as "os", "time" and "net". Use those packages rather than this one if you can. For details of the functions and data types in this package consult the manuals for the appropriate operating system. These calls return err == nil to indicate success; otherwise err is an operating system error describing the failure. On most systems, that error has type syscall.Errno. </p>
<p>NOTE: Most of the functions, types, and constants defined in this package are also available in the <span>golang.org/x/sys</span> package. That package has more system call support than this one, and most new code should prefer that package where possible. See <a href="https://golang.org/s/go1.4-syscall">https://golang.org/s/go1.4-syscall</a> for more information. </p>     <h2 id="pkg-index">Index </h2>  <ul id="manual-nav">

<p>We want the child in a fork/exec sequence to inherit only the file descriptors we intend. To do that, we mark all file descriptors close-on-exec and then, in the child, explicitly unmark the ones we want the exec'ed program to keep. Unix doesn't make this easy: there is, in general, no way to allocate a new file descriptor close-on-exec. Instead you have to allocate the descriptor and then mark it close-on-exec. If a fork happens between those two events, the child's exec will inherit an unwanted file descriptor. </p>
<p>This lock solves that race: the create new fd/mark close-on-exec operation is done holding ForkLock for reading, and the fork itself is done holding ForkLock for writing. At least, that's the idea. There are some complications. </p>
<p>Some system calls that create new file descriptors can block for arbitrarily long times: open on a hung NFS server or named pipe, accept on a socket, and so on. We can't reasonably grab the lock across those operations. </p>
<p>It is worse to inherit some file descriptors than others. If a non-malicious child accidentally inherits an open ordinary file, that's not a big deal. On the other hand, if a long-lived child accidentally inherits the write end of a pipe, then the reader of that pipe will not see EOF until that child exits, potentially causing the parent program to hang. This is a common problem in threaded C programs that use popen. </p>
<p>Luckily, the file descriptors that are most important not to inherit are not the ones that can take an arbitrarily long time to create: pipe returns instantly, and the net package uses non-blocking I/O to accept on a listening socket. The rules for which file descriptor-creating operations use the ForkLock are as follows: </p>
<ul> <li>Pipe. Use pipe2 if available. Otherwise, does not block, so use ForkLock. </li>
<li>Socket. Use SOCK_CLOEXEC if available. Otherwise, does not block, so use ForkLock. </li>
<li>Open. Use O_CLOEXEC if available. Otherwise, may block, so live with the race. </li>
<li>Dup. Use F_DUPFD_CLOEXEC or dup3 if available. Otherwise, does not block, so use ForkLock. </li>
</ul> <pre data-language="go">var ForkLock sync.RWMutex</pre> <p>For testing: clients can set this flag to force creation of IPv6 sockets to return EAFNOSUPPORT. </p>
