Missing basic wide char/wide string handling functions

Missing basic wide char/wide string handling functions

[Kirwan, Brian]

Hi,

I'm building an application that needs to handle unicode strings and
therefore need wide char/string handling functions.  In gcc, I CAN find the
corresponding CONVERSION functions (e.g., mbstowcs, wcstombs, etc.) but I
CANNOT find the BASIC wide string handling functions, i.e., wcout, wstrcat,
etc. (nor wprintf, etc in the C library).

I've tried building various different versions from source (2.95.3, 3.0,
3.0.1, 3.0.2) and I've also downloaded the pre-built versions from the Sun
freeware site but none of them seem to support these basic functions.

I would be very grateful if someone could let me know if either:

*	these functions arent supported
*	I need to build/configure gcc some other way to get them
*	maybe they have some other slightly different name in gcc(?)

Thanks in advance,

GCC makes a few POSIX-like fixes to the system header files, but the set
of functions you have really depends on the C library you're using and
not on the compiler.

That said, it sounds like you're using a Sun box. Certainly Solaris
2.8's system C library has wprintf in wchar.h (try 'man wprintf') but
I'm not sure how many Solaris versions back that goes.

Hope that helps,
Rup.

Hi Rupert,

Thanks for your quick respose.

You're right - I'm on Solaris. Its 2.6 whose wchar.h doesnt have wprintf.
I've checked a 2.8 machine and you're right - its wchar.h does have it.

So, Solaris 2.8's C library supports it.

But, as for the C++ side (which I would prefer), shouldnt GCC's iostream
support wcout (which it doesnt seem to do)?

Thanks very much,
Brian.
