 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
