int
ostream::opfx ()
Method
opfx
is a prefix method for operations on ostream
objects; it is designed to be called before any further processing. See
the following method, ostream::osfx,
for the converse of opfx
functionality.
opfx
tests that the stream is in state good,
and if so flushes any stream tied to this one. The result is 1
when opfx
succeeds; else (if the stream state is not good),
the result is 0.
void
ostream::osfx ()
Method
osfx
is a suffix method for operations on ostream
objects; it is designed to be called at the conclusion of any processing.
All the ostream
methods end by calling osfx.
See the previous method, ostream::opfx,
for the converse of osfx
functionality. If the unitbuf
flag is set for this stream, osfx
flushes any buffered output for it.
If the stdio
flag is set for this stream, osfx
flushes any output buffered for the C output streams, stdout
and stderr.
