+@deftypefn Extension int vasprintf (char **@var{resptr}, char *@var{format}, va_list @var{args})
+
+Like @code{vsprintf}, 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{vsprintf} would return. If memory could
+not be allocated, zero is returned and @code{NULL} is stored in
+@code{*@var{resptr}}.
