Could Rvsnprintf (in src/main/errors.c) be added to the R API
with prototype in include/R_ext/Print.h say?
Here's my problem. I'm trying to write some code that is not
totally tied to R. Hence I want R style error messaging to
be isolated in a small module. I do not want #include <R.h>
and calls to error (Rf_error) in most of my code.
Hence I want to write a module with something like
----- begin code snippet -----
#include <stdarg.h>
#include <stdio.h>
#include <R.h>
#define BUFSIZE 1024
void die(const char *format, ...)
{
char buf[BUFSIZE];
va_list arg;
va_start(arg, format);
vsnprintf(buf, BUFSIZE, format, arg);
va_end(arg);
buf[BUFSIZE - 1] = '\0';
error(buf);
}
----- end code snippet -----
But that's not portable because vsnprintf isn't.
You've already made a big effort to work around nonportability of
vsnprintf, but don't make it available in the API. Why not?
If I could change vsnprintf to Rvsnprintf above, then I wouldn't
have to do some horrible autoconf song and dance that probably wouldn't
be completely portable anyway.
Or is there a better solution I haven't seen?
