Creates a symbolic link.

To perform this operation as a transacted operation, use the CreateSymbolicLinkTransacted function.

Syntax

BOOLEAN WINAPI CreateSymbolicLink(
  __in  LPTSTR lpSymlinkFileName,
  __in  LPTSTR lpTargetFileName,
  __in  DWORD dwFlags
);

Parameters

lpSymlinkFileName [in]

The symbolic link to be created.

lpTargetFileName [in]

The name of the target for the symbolic link to be created.

If lpTargetFileName has a device name associated with it, the link is treated as an absolute link; otherwise, the link is treated as a relative link.

dwFlags [in]

Indicates whether the link target, lpTargetFileName, is a directory.

Value	Meaning
0x0	The link target is a file.
SYMBOLIC_LINK_FLAG_DIRECTORY 0x1	The link target is a directory.

 

Return Value

If the function succeeds, the return value is nonzero.

If the function fails, the return value is zero. To get extended error information, call GetLastError.

Remarks

Symbolic links can either be absolute or relative links. Absolute links are links that specify each portion of the path name; relative links are determined relative to where relative–link specifiers are in a specified path. Relative links are specified using the following conventions:

• Dot (. and ..) conventions—for example, "..\" resolves the path relative to the parent directory.
• Names with no slashes (\)—for example, "tmp" resolves the path relative to the current directory.
• Root relative—for example, "\windows\system32" resolves to <current drive>:\windows\system32.
• Current working directory–relative—for example, if the current working directory is c:\windows\system32, "c:file.txt" resolves to c:\windows\system32\file.txt.

  Note  If you specify a current working directory–relative link, it is created as an absolute link, due to the way the current working directory is processed based on the user and the thread.
