47 You can pass a preallocated buffer for the result in RESULTBUF and its
48 size in *LENGTHP; otherwise you pass RESULTBUF = NULL.
49 If successful, return the address of the string (this may be = RESULTBUF
50 if no dynamic memory allocation was necessary) and set *LENGTHP to the
51 number of resulting bytes, excluding the trailing NUL. Upon error, set
52 errno and return NULL.
54 When dynamic memory allocation occurs, the preallocated buffer is left
55 alone (with possibly modified contents). This makes it possible to use
56 a statically allocated or stack-allocated buffer, like this:
59 size_t len = sizeof (buf);
60 char *output = vasnprintf (buf, &len, format, args);
62 ... error handling ...;
