Description

/* **************************************** */

static inline int safe_snprintf(char *str, size_t size, const char *format, ...)
{{{ .... }}}

This function fails for size = 0, and ... inside it calls vsnprintf, without considering that in case of error vsnprintf returns a negative number.

PR in progress.
