| 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}}. |
