25 <<open_memstream>> creates a seekable, byte-oriented <<FILE>> stream that
26 wraps an arbitrary-length buffer, created as if by <<malloc>>. The current
27 contents of *<[buf]> are ignored; this implementation uses *<[size]>
28 as a hint of the maximum size expected, but does not fail if the hint
29 was wrong. The parameters <[buf]> and <[size]> are later stored
31 current address and usable size of the allocated string; although
34 either *<[buf]> or *<[size]> prior to <<fclose>>.
