memory_ostream class ¶The memory_ostream class supports output to an in-memory buffer.
Its type is ‘memory_ostream_t’. It is a subclass of
‘ostream_t’.
It can be instantiated through this function:
memory_ostream_t memory_ostream_create (void) ¶Creates an output stream that accumulates the output in a memory buffer.
The class adds the following method:
void memory_ostream_contents (memory_ostream_t stream, const void **bufp, size_t *buflenp) ¶Returns a pointer to the output accumulated so far and its size. It
stores them in *bufp and *buflenp, respectively.
Note: These two return values become invalid when more output is done to the stream or when the stream is freed.
