Hello Michael, Wainer,
It's weird. The only manual page that I've seen using restrict, and I
think it's wrong. glibc doesn't use it:
.../glibc$ grep_glibc_prototype strfromd
src/gnu/glibc/stdlib/stdlib.h:212:
extern int strfromd (char *__dest, size_t __size, const char *__format,
double __f)
__THROW __nonnull ((3));
.../glibc$ grep_glibc_prototype strfromf
src/gnu/glibc/stdlib/stdlib.h:216:
extern int strfromf (char *__dest, size_t __size, const char *__format,
float __f)
__THROW __nonnull ((3));
.../glibc$ grep_glibc_prototype strfroml
src/gnu/glibc/stdlib/stdlib.h:220:
extern int strfroml (char *__dest, size_t __size, const char *__format,
long double __f)
__THROW __nonnull ((3));
.../glibc$
And the manual page states that it conforms to some standards, but I
haven't found it in C99 (neither in C11 nor C18) nor in POSIX:
$ man 3 strfromd | sed -n '/CONFORMING/,/^$/p'
CONFORMING TO
C99, ISO/IEC TS 18661-1.
$ man 3p strfromd
No manual entry for strfromd in section 3p
$
I don't know what that other "ISO/IEC TS 18661-1" is.

Should I remove restrict? And C99 from the CONFORMING TO section?
Thanks,
Alex
