%ls C89?

[Servé Lau]

Is the %ls format specifier C99 or was it also in C89? For me this is a very
handy feature

#include <stdio.h>
#include <wchar.h>

int main(void) {
wchar_t buf[128];

sscanf("hello", "%ls", buf);

fwprintf(stdout, buf);

return 0;
}

As far as I can tell, 'l' cannot be used as a length modifier for 's',
'c', or '[' in C89.

#include <stdio.h>
#include <wchar.h>

int main(void) {
wchar_t buf[128];

sscanf("hello", "%ls", buf);

fwprintf(stdout, buf);

return 0;
}

Neither <wchar.h> nor fwprintf() exist in C89, either (they were added
with Normative Addendum 1, so they are part of C95).

Also, I just noticed that the 'l' length modifier was also added for the
printf and scanf functions with Normative Addendum 1, so they are C95
and C99, but not C89. C95 is fairly wide-spread I think, so you may be
OK to use them. gcc and MS Visual C both support C95, I believe.

Since we're talking about library features, gcc's support for C95 is
irrelevant.

I've no idea how widely implemented the C95 library features are.
