The Carbon toolbox uses this * API itself when translating CFStrings to Pascal strings. * GetTextAndEncodingFromCFString attempts to convert the Unicode * characters in the string to the closest non-Unicode * representation of the string. For example, a string containing * only Unicode characters that are present in the MacRoman one-byte * encoding will be translated to MacRoman, and * kTextEncodingMacRoman will be returned as the encoding of the * text. A string containing Unicode characters that are present in * the MacJapanese two-byte encoding will be translated to * MacJapanese (Shift-JIS), and kTextEncodingMacJapanese will be * returned as the encoding of the text. * GetTextAndEncodingFromCFString is designed to be used for simple * strings which contain only text from a single language. It is not * designed to translate strings with multiple runs of text from * different languages, and will only return the first run of such a * string; for example, if you pass it a string containing a run of * Roman characters followed by a run of Japanese characters, it * will only return the Roman characters in the output buffer. For * more complex text translation, you should call the Unicode * converter directly (see ConvertFromUnicodeToTextRun, which * GetTextAndEncodingFromCFString uses internally). * * Mac OS X threading: * Not thread safe * * Parameters: * * inString: * The string to convert. * * outText: * The output buffer in which to place the converted text. * * inTextMaxLength: * The length in bytes of the input buffer. * * outTextLength: * On exit, contains the length in bytes of the text that was * placed into the output buffer. * * outEncoding: * On exit, contains the encoding of the text that was placed into * the output buffer. * * Availability: * Mac OS X: in version 10.0 and later in Carbon.framework * CarbonLib: in CarbonLib 1.2.5 and later * Non-Carbon CFM: not available } function GetTextAndEncodingFromCFString( inString: CFStringRef; outText: BytePtr; inTextMaxLength: ByteCount; var outTextLength: ByteCount; outEncoding: TextEncodingPtr { can be NULL } ): OSStatus; external name '_GetTextAndEncodingFromCFString'; (* AVAILABLE_MAC_OS_X_VERSION_10_0_AND_LATER *) end.
