Function Documentation

char* convert_from_fs ( const TCHAR *  name,
char *  utf8_buf,
size_t  buflen 
)

Convert to OpenTTD's encoding from that of the environment in UNICODE.

OpenTTD encoding is UTF8, local is wide

Parameters
namepointer to a valid string that will be converted
utf8_bufpointer to a valid buffer that will receive the converted string
buflenlength in characters of the receiving buffer
Returns
pointer to utf8_buf. If conversion fails the string is of zero-length

TCHAR* convert_to_fs ( const char *  name,
TCHAR *  system_buf,
size_t  buflen,
bool  console_cp 
)

Convert from OpenTTD's encoding to that of the environment in UNICODE.

OpenTTD encoding is UTF8, local is wide

Parameters
namepointer to a valid string that will be converted
utf16_bufpointer to a valid wide-char buffer that will receive the converted string
buflenlength in wide characters of the receiving buffer
console_cpconvert to the console encoding instead of the normal system encoding.
Returns
pointer to utf16_buf. If conversion fails the string is of zero-length

const char* FS2OTTD ( const TCHAR *  name)

Convert to OpenTTD's encoding from that of the local environment.

When the project is built in UNICODE, the system codepage is irrelevant and the input string is wide. In ANSI mode, the string is in the local codepage which we'll convert to wide-char, and then to UTF-8. OpenTTD internal encoding is UTF8. The returned value's contents can only be guaranteed until the next call to this function. So if the value is needed for anything else, use convert_from_fs

Parameters
namepointer to a valid string that will be converted (local, or wide)
Returns
pointer to the converted string; if failed string is of zero-length

bool GetClipboardContents ( char *  buffer,
const char *  last 
)

Try to retrieve the current clipboard contents.

Note
OS-specific function.
Parameters
bufferClipboard content.
lastThe pointer to the last element of the destination buffer
Returns
True if some text could be retrieved.

uint GetCPUCoreCount ( )

Get number of processor cores in the system, including HyperThreading or similar.

Returns
Total number of processor cores.

const char* GetCurrentLocale ( const char *  )

Determine the current user's locale.

const TCHAR* OTTD2FS ( const char *  name,
bool  console_cp 
)

Convert from OpenTTD's encoding to that of the local environment.

When the project is built in UNICODE the system codepage is irrelevant and the converted string is wide. In ANSI mode, the UTF8 string is converted to multi-byte. OpenTTD internal encoding is UTF8. The returned value's contents can only be guaranteed until the next call to this function. So if the value is needed for anything else, use convert_from_fs

Parameters
namepointer to a valid string that will be converted (UTF8)
console_cpconvert to the console encoding instead of the normal system encoding.
Returns
pointer to the converted string; if failed string is of zero-length

HRESULT OTTDSHGetFolderPath ( HWND  hwnd,
int  csidl,
HANDLE  hToken,
DWORD  dwFlags,
LPTSTR  pszPath 
)

Our very own SHGetFolderPath function for support of windows operating systems that don't have this function (eg Win9x, etc.).

We try using the native function, and if that doesn't exist we will try a more crude approach of environment variables and hope for the best
