Description

The FLI :ef-wc-string type converts between a Lisp string and a C wide-character string. The C string may have a maximum length of limit characters.

The external-format is used to specify the format of the foreign string. It defaults to a format appropriate for C string of type wchar_t* . For Unicode encoded strings, specify :unicode . If you want to pass a string to the Windows API, known as STR in the Windows API terminology, specify win32:*multibyte-code-page-ef* , which is a variable holding the external format corresponding to the current Windows multi-byte code page.
