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 |
||
40 | @code{*@var{resptr}}. |
