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 syscall.Errno.

Deprecated: this package is locked down. Callers should use the corresponding package in the golang.org/x/sys repository instead. That is also where updates required by new systems or versions should be applied. See https://golang.org/s/go1.4-syscall for more information.

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.

Only a limited number of callbacks may be created in a single Go process, and any memory allocated for these callbacks is never released.

type LazyDLL

type LazyDLL struct {
	Name string
	// contains filtered or unexported fields
}

A LazyDLL implements access to a single DLL. It will delay the load of the DLL until the first call to its 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.

func NewLazyDLL

func NewLazyDLL(name string) *LazyDLL

NewLazyDLL creates new LazyDLL associated with DLL file.

func (*LazyDLL) Handle

func (d *LazyDLL) Handle() uintptr

Handle returns d's module handle.

func (*LazyDLL) Load

func (d *LazyDLL) Load() error

Load loads DLL file d.Name into memory. It returns an error if fails. Load will not try to load DLL, if it is already loaded into memory.

func (*LazyDLL) NewProc

func (d *LazyDLL) NewProc(name string) *LazyProc

NewProc returns a LazyProc for accessing the named procedure in the DLL d.

type LazyProc

type LazyProc struct {

}

A LazyProc implements access to a procedure inside a LazyDLL. It delays the lookup until the Addr, Call, or Find method is called.

func (*LazyProc) Addr

func (p *LazyProc) 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 (*LazyProc) Call

func (p *LazyProc) Call(a ...uintptr) (r1, r2 uintptr, lastErr error)

Call executes procedure p with arguments a. See the documentation of Proc.Call for more information.

func (*LazyProc) Find

func (p *LazyProc) Find() error

Find searches DLL for procedure named p.Name. It returns an error if search fails. Find will not search procedure, if it is already found and loaded into memory.

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) (r1, r2 uintptr, lastErr error)

Call executes procedure p with arguments a. It will panic if more than 18 arguments are supplied.

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 syscall.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)).
