32 @deftypefn Extension int asprintf (char **@var{resptr}, const char *@var{format}, ...)
34 Like @code{sprintf}, but instead of passing a pointer to a buffer, you
35 pass a pointer to a pointer. This function will compute the size of
36 the buffer needed, allocate memory with @code{malloc}, and store a
37 pointer to the allocated memory in @code{*@var{resptr}}. The value
38 returned is the same as @code{sprintf} would return. If memory could
39 not be allocated, minus one is returned and @code{NULL} is stored in
47 asprintf (char **buf
, const char *fmt
, ...)
52 status
= vasprintf (buf
, fmt
, ap
);
