[Cfp-interest 1496] Re: AI item to submit proposal about why no wide string strfrom functions

[Mike Cowlishaw]

Hmm, given the uncertainty about 

int nc = strfromd(s, n, "%g", d);

... perhaps just change that line to use snprintf, which has 'well-known'
behaviour?

Here's an update for the code segment: 


#include <stdlib.h>

const size_t n = 20;

double d;

.

// convert d to single-byte character string s

char s[n];

int nc = strfromd(s, n, "%g", d);

// convert s (regarded as a multi-byte character 

// string) to wide string ws

wchar_t ws[n];

(void)mbstowcs(ws, s, n);

Probably so. the other code examples in the C standard include all the
declarations. Update to follow.

Do you need a declaration for the wide string 'ws' in that code at the end?
