Like @code{sprintf}, 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{sprintf} would return. If memory could
|
|
not be allocated, minus one is returned and @code{NULL} is stored in
|
|
@code{*@var{resptr}}.
