DISCUSSION

The TECCountAvailableTextEncodings function counts and returns the number of text encodings that you can use to perform conversions based on the current configuration of the Text Encoding Converter. This number indicates what size array you must allocate in a parameter of the function TECGetAvailableTextEncodings. Therefore, you should call this function before you call TECGetAvailableTextEncodings in order to accommodate the specifications for all of these text encodings.

TECCountAvailableTextEncodings counts each instance of the same encoding. That is, if different conversion plug-ins support the same text encoding for any of the conversion processes they provide, this function includes each instance of the text encoding in its sum. Consequently, the same text encoding may be counted more than once. For example, the Japanese Encodings plug-in supports Mac OS Japanese, and so does the Unicode Encodings plug-in. However, since the TECGetAvailableTextEncodings function does not return duplicate text encoding specifications, TECCountAvailableTextEncodings may return a number greater than the number of array elements required.
