[其他] 获得自身路径的函数是什么？

GetModuleFileName
The GetModuleFileName function retrieves the fully qualified path for the specified module.

To specify the process that contains the module, use the GetModuleFileNameEx function.

DWORD GetModuleFileName(
  HMODULE hModule,    // handle to module
  LPTSTR lpFilename,  // path buffer
  DWORD nSize         // size of buffer
);

TCHAR t_tcaPath[MAX_PATH];
GetModuleFileName( AfxGetInstanceHandle(), t_tcaPath, MAX_PATH);

GetShortPathName
The GetShortPathName function retrieves the short path form of a specified input path.

DWORD GetShortPathName(
  LPCTSTR lpszLongPath,  // null-terminated path string
  LPTSTR lpszShortPath,  // short form buffer
  DWORD cchBuffer        // size of short form buffer
);
Parameters
lpszLongPath
[in] Pointer to a null-terminated path string. The function retrieves the short form of this path.
Windows NT/2000/XP: In the ANSI version of this function, the name is limited to MAX_PATH characters. To extend this limit to nearly 32,000 wide characters, call the Unicode version of the function and prepend "\\?\" to the path. For more information, see File Name Conventions.

Windows 95/98/Me: This string must not exceed MAX_PATH characters.

lpszShortPath
[out] Pointer to a buffer to receive the null-terminated short form of the path specified by lpszLongPath.
cchBuffer
[in] Specifies the size, in TCHARs, of the buffer pointed to by lpszShortPath.

GetLongPathName
The GetLongPathName function converts the specified path to its long form. If no long path is found, this function simply returns the specified name.

DWORD GetLongPathName(
  LPCTSTR lpszShortPath, // file name
  LPTSTR lpszLongPath,   // path buffer
  DWORD cchBuffer        // size of path buffer
);
Parameters
lpszShortPath
[in] Pointer to a null-terminated path to be converted.
Windows 2000/XP: In the ANSI version of this function, the name is limited to MAX_PATH characters. To extend this limit to nearly 32,000 wide characters, call the Unicode version of the function and prepend "\\?\" to the path. For more information, see File Name Conventions.

Windows 98/Me: This string must not exceed MAX_PATH characters.

lpszLongPath
[out] Pointer to the buffer to receive the long path. You can use the same buffer you used for the lpszShortPath parameter.
cchBuffer
[in] Specifies the size of the buffer, in TCHARs.
