While we're on the topic and I already have two experts watching this thread, is snprintf-posix helpful in order to use the following portably? length = snprintf (NULL, 0, format, args); str = malloc (length + 1); snprintf (str, length + 1, format, args); The snprintf man page warns of portability problems here, but snprintf-posix only appears to test vsnprintf's functionality for this purpose by invoking gl_VSNPRINTF_ZEROSIZE_C99. Is it just assumed snprintf and vsnprintf will be consistent in this respect? Also, is there any single module that ensures portability of all *printf functions, or should I include every *printf-posix module individually in order to ensure consistent behavior? If I should add bug-gnulib, let me know.
