Documentation

Overview

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 Errno.

NOTE: Most of the functions, types, and constants defined in this package are also available in the golang.org/x/sys package. That package has more system call support than this one, and most new code should prefer that package where possible. See https://golang.org/s/go1.4-syscall for more information.

func NewCallback

func NewCallback(fn any) uintptr

NewCallback converts a Go function to a function pointer conforming to the stdcall calling convention. This is useful when interoperating with Windows code requiring callbacks. The argument is expected to be a function with one uintptr-sized result. The function must not have arguments with size larger than the size of uintptr. Only a limited number of callbacks may be created in a single Go process, and any memory allocated for these callbacks is never released. Between NewCallback and NewCallbackCDecl, at least 1024 callbacks can always be created.

func NewCallbackCDecl added in go1.3

func NewCallbackCDecl(fn any) uintptr

NewCallbackCDecl converts a Go function to a function pointer conforming to the cdecl calling convention. This is useful when interoperating with Windows code requiring callbacks. The argument is expected to be a function with one uintptr-sized result. The function must not have arguments with size larger than the size of uintptr. Only a limited number of callbacks may be created in a single Go process, and any memory allocated for these callbacks is never released. Between NewCallback and NewCallbackCDecl, at least 1024 callbacks can always be created.

func RegEnumKeyEx(key Handle, index uint32, name *uint16, nameLen *uint32, reserved *uint32, class *uint16, classLen *uint32, lastWriteTime *Filetime) (regerrno error)

RegEnumKeyEx enumerates the subkeys of an open registry key. Each call retrieves information about one subkey. name is a buffer that should be large enough to hold the name of the subkey plus a null terminating character. nameLen is its length. On return, nameLen will contain the actual length of the subkey.

Should name not be large enough to hold the subkey, this function will return ERROR_MORE_DATA, and must be called again with an appropriately sized buffer.

reserved must be nil. class and classLen behave like name and nameLen but for the class of the subkey, except that they are optional. lastWriteTime, if not nil, will be populated with the time the subkey was last written.

The caller must enumerate all subkeys in order. That is RegEnumKeyEx must be called with index starting at 0, incrementing the index until the function returns ERROR_NO_MORE_ITEMS, or with the index of the last subkey (obtainable from RegQueryInfoKey), decrementing until index 0 is enumerated.

Successive calls to this API must happen on the same OS thread, so call runtime.LockOSThread before calling this function.

type LazyDLL

type LazyDLL struct {

A LazyDLL implements access to a single DLL. It will delay the load of the DLL until the first call to its LazyDLL.Handle method or to one of its LazyProc's Addr method.

LazyDLL is subject to the same DLL preloading attacks as documented on LoadDLL.

Use LazyDLL in golang.org/x/sys/windows for a secure way to load system DLLs.

type Pointer added in go1.11

type Pointer *struct{}

Pointer represents a pointer to an arbitrary Windows type.

Pointer-typed fields may point to one of many different types. It's up to the caller to provide a pointer to the appropriate type, cast to Pointer. The caller must obey the unsafe.Pointer rules while doing so.

type Proc

type Proc struct {
	Dll  *DLL
	Name string
	// contains filtered or unexported fields
}

A Proc implements access to a procedure inside a DLL.

func (*Proc) Addr

func (p *Proc) Addr() uintptr

Addr returns the address of the procedure represented by p. The return value can be passed to Syscall to run the procedure.

func (*Proc) Call

func (p *Proc) Call(a ...uintptr) (uintptr, uintptr, error)

Call executes procedure p with arguments a.

The returned error is always non-nil, constructed from the result of GetLastError. Callers must inspect the primary return value to decide whether an error occurred (according to the semantics of the specific function being called) before consulting the error. The error always has type Errno.

On amd64, Call can pass and return floating-point values. To pass an argument x with C type "float", use uintptr(math.Float32bits(x)). To pass an argument with C type "double", use uintptr(math.Float64bits(x)). Floating-point return values are returned in r2. The return value for C type "float" is math.Float32frombits(uint32(r2)). For C type "double", it is math.Float64frombits(uint64(r2)).
