@deftypefn Extension int asprintf (char **@var{resptr}, const char *@var{format}, ...)
Like @code{sprintf}, but instead of passing a pointer to a buffer, you
pass a pointer to a pointer. This function will compute the size of
the buffer needed, allocate memory with @code{malloc}, and store a
pointer to the allocated memory in @code{*@var{resptr}}. The value
returned is the same as @code{sprintf} would return. If memory could
not be allocated, minus one is returned and @code{NULL} is stored in
@code{*@var{resptr}}.
@end deftypefn
