WSTRING_TO_STRING2
The function converts a variable of the data type WSTRING into a variable of the data type STRING.
The function returns
- TRUE if the conversion of the complete string was possible.
- FALSE if the input string is longer than the output string and the result doesn't fit in the given output buffer.
Characters that cannot be converted are skipped during the conversion.
The function stops the conversion after Parameterlist.cMaxCharacters characters in order to avoid an infinite loop.
