syscall

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.

NOTE: This package is locked down. Code outside the standard Go repository should be migrated to use the corresponding package in the golang.org/x/sys repository. 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.

Functions

func BytePtrFromString

func BytePtrFromString(s string) (*byte, error)

BytePtrFromString returns a pointer to a NUL-terminated array of bytes containing the text of s. If s contains a NUL byte at any location, it returns (nil, EINVAL).

func ByteSliceFromString

func ByteSliceFromString(s string) ([]byte, error)

ByteSliceFromString returns a NUL-terminated slice of bytes containing the text of s. If s contains a NUL byte at any location, it returns (nil, EINVAL).

func Getpagesize

func Getpagesize() int

func StringBytePtr

func StringBytePtr(s string) *byte

StringBytePtr returns a pointer to a NUL-terminated array of bytes. If s contains a NUL byte this function panics instead of returning an error.

Deprecated: Use BytePtrFromString instead.

func StringByteSlice

func StringByteSlice(s string) []byte

StringByteSlice converts a string to a NUL-terminated []byte, If s contains a NUL byte this function panics instead of returning an error.

Deprecated: Use ByteSliceFromString instead.
