/* Write formatted output to a string dynamically allocated with malloc().
|
|
You can pass a preallocated buffer for the result in RESULTBUF and its
|
|
size in *LENGTHP; otherwise you pass RESULTBUF = NULL.
|
|
If successful, return the address of the string (this may be = RESULTBUF
|
|
if no dynamic memory allocation was necessary) and set *LENGTHP to the
|
|
number of resulting bytes, excluding the trailing NUL. Upon error, set
|
|
errno and return NULL.
|
|
|
|
When dynamic memory allocation occurs, the preallocated buffer is left
|
|
alone (with possibly modified contents). This makes it possible to use
|
|
a statically allocated or stack-allocated buffer, like this:
|
|
|
|
char buf[100];
|
|
size_t len = sizeof (buf);
|
|
char *output = vasnprintf (buf, &len, format, args);

... error handling ...;

else

... use the output string ...;
