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.
