Description
Ultibo Widestring Manager Interface unit
This unit implements the WideString and UnicodeString support for Ultibo including the WideStringManager/UnicodeStringManager interface for the RTL.
This unit provides compatible implementations of the following functions:
- CharLower
- CharPrev
- CharUpper
- FoldString
- GetStringTypeEx
- IsCharAlphaNumeric
- IsDBCSLeadByte
- LoadString
- lstrcmpi
- lstrlen
- OemToCharBuff
- wvsprintf
- OemToAnsi
- CharLowerBuff
- CharToOem
- CharUpperBuff
- FormatMessage
- GetStringTypeW
- IsCharLower
- IsTextUnicode
- lstrcat
- lstrcpy
- MultiByteToWideChar
- WideCharToMultiByte
- CompareStringW
- CharNext
- CharToOemBuff
- CompareStringA
- GetStringTypeA
- IsCharAlpha
- IsCharUpper
- LCMapString
- lstrcmp
- lstrcpyn
- OemToChar
- wsprintf
- AnsiToOem
The following functions are implemented by the FileSystem unit:
- AreFileApisANSI (AreFileApisANSI is exposed in the Ultibo unit)
- SetFileApisToANSI (SetFileApisToANSI is exposed in the Ultibo unit)
- SetFileApisToOEM (SetFileApisToOEM is exposed in the Ultibo unit)
Most of the above are currently not implemented.

Unicode functions
function MultiByteToWideChar(CodePage:UINT; dwFlags:DWORD; lpMultiByteStr:LPCSTR; cbMultiByte:Integer; lpWideCharStr:LPWSTR; cchWideChar:Integer):Integer;
Note | cchWideChar is the size of lpWideCharStr in WideChars (not Bytes).
Currently ignores the Flags parameter. Currently only supports SBCS. |
---|
function WideCharToMultiByte(CodePage:UINT; dwFlags:DWORD; lpWideCharStr:LPCWSTR; cchWideChar:Integer; lpMultiByteStr:LPSTR; cbMultiByte:Integer; lpDefaultChar:LPCSTR; lpUsedDefaultChar:LPBOOL):Integer;
Note | cchWideChar is the size of lpWideCharStr in WideChars (not Bytes).
Currently ignores the Flags and DefaultChar parameters. Currently only supports SBCS. |

function CompareStringA(Locale:LCID; dwCmpFlags:DWORD; lpString1:LPCSTR; cchCount1:Integer; lpString2:LPCSTR; cchCount2:Integer):Integer;
Note | Currently the Locale value is ignored and the ANSI code page is used for comparison.
Currently only supports SBCS. |

function CompareStringW(Locale:LCID; dwCmpFlags:DWORD; lpString1:LPCWSTR; cchCount1:Integer; lpString2:LPCWSTR; cchCount2:Integer):Integer;

Note | None documented |
---|
function CharUpperA(lpsz:LPSTR):LPSTR;
Note | Unlike Windows this function does not differentiate a single character by the high order word of the passed pointer. To convert a single character call CharUpperBuffA instead with the length as 1.
Currently only supports SBCS. |
