NB, we have to use a %s format string when going via gettext rather than

ACK, this looks good to me now.

Okidoc, applied and commited to CVS,
thanks !

Whatever its name, please do two more things:
- add "ATTRIBUTE_FORMAT(printf, 3, 4)" before the semicolon, so that
gcc -Wformat compares the format string with types of corresponding arguments.
(this must be done with any varargs "..." printf/scanf-style function)
- add the new name to the list in Makefile.cfg (msg_gen_function),

Hum, maybe we could just rename the one in remote_internal.c to rem_error()
to avoid confusion.

Everything seems fixed with his latest patch :-)
thanks I completely missed those points !

Hum, maybe we could just rename the one in remote_internal.c to rem_error()
to avoid confusion.
The fact that every single driver duplicates the same code to wrap
__virRaiseError suggests we need simpler shared version to me. The
only thing that differs is the VIR_FROM_QEMU, FROM_XEN, etc, param
I'd suggest we add a
__virRaiseSimpleError(virConnectPtr conn, int from, int code, const cha *fmt, ...)
{
va_list args;
char errorMessage[1024];
const char *virerr;
if (fmt) {
va_start(args, fmt);
vsnprintf(errorMessage, sizeof(errorMessage)-1, fmt, args);
va_end(args);
} else {
errorMessage[0] = '\0';
}
virerr = __virErrorMsg(code, (errorMessage[0] ? errorMessage : NULL));
__virRaiseError(conn, dom, net, from, code, VIR_ERR_ERROR,
virerr, errorMessage, NULL, -1, -1, virerr, errorMessage);
}
and then each driver can 'wrap' it with a macro
#define ERROR(conn, code, fmt, ...) \
__virRaiseeSimpleError((conn), VIR_FROM_QEMU, (code), (fmt), __VA_ARGS__)
