| 50 | Like @code{vsprintf}, but instead of passing a pointer to a buffer,
|
|---|
| 51 | you pass a pointer to a pointer. This function will compute the size
|
|---|
| 52 | of the buffer needed, allocate memory with @code{malloc}, and store a
|
|---|
| 53 | pointer to the allocated memory in @code{*@var{resptr}}. The value
|
|---|
| 54 | returned is the same as @code{vsprintf} would return. If memory could
|
|---|
| 55 | not be allocated, zero is returned and @code{NULL} is stored in
|
|---|
| 56 | @code{*@var{resptr}}.
