The maximum number of characters of the C wide-character string.
An external format specification.
null-terminated-p
A boolean controlling the null termination byte.
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
limit
can be omitted in cases where a new foreign string is being allocated.
The
external-format
is used to specify the encoding of the foreign string. It defaults to an encoding 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
WSTR
in the Windows API terminology, also specify
:unicode.
To change the default, call set-locale or set-locale-encodings.
If
null-terminated-p
is non-
nil
, a NULL word is added to the end of the string.
