:redir >name_of_registers_file :registers :redir END :r name_of_registers_file :help redir The last command is very useful, since there are lots of options for redirection: to variables, to registers, how to append, further cornucopia. I still find it weird and annoying that it uses END that way, but since everything else that can follow redir has to … Read more
The other answers tell you that the pipe size is 64 KB. The reason why PIPE_BUF is 4KB is that PIPE_BUF is the largest size for which writes are guaranteed to be atomic. See http://pubs.opengroup.org/onlinepubs/9699919799/functions/write.html
I looked at the ruby documentation for StringIO, and it looks like what you want is StringIO#string, not StringIO#to_s Thus, change your code to: s = StringIO.new s << ‘foo’ s << ‘bar’ s.string
Files are already buffered by the file system cache. You just need to pick a buffer size that doesn’t force FileStream to make the native Windows ReadFile() API call to fill the buffer too often. Don’t go below a kilobyte, more than 16 KB is a waste of memory and unfriendly to the CPU’s L1 … Read more
Assuming you’re using log4net out of the box, you can dig your way down & flush the appender like this: public void FlushBuffers() { ILog log = LogManager.GetLogger(“whatever”); var logger = log.Logger as Logger; if (logger != null) { foreach (IAppender appender in logger.Appenders) { var buffered = appender as BufferingAppenderSkeleton; if (buffered != null) … Read more
Basically, you need to use the readFile or readFileSync function from the fs module. They return the complete content of the given file, but differ in their behavior (asynchronous versus synchronous). If blocking Node.js (e.g. on startup of your application) is not an issue, you can go with the synchronized version, which is as easy … Read more
According to Brad Abrams, almost never: link No, there is zero benefit from wrapping a BufferedStream around a FileStream. We copied BufferedStream’s buffering logic into FileStream about 4 years ago to encourage better default performance… In fact, I don’t think there are any Streams in the .NET Framework that require it, but it might be … Read more
If you intend to store arbitrary binary data, you should use unsigned char. It is the only data type that is guaranteed to have no padding bits by the C Standard. Each other data type may contain padding bits in its object representation (that is the one that contains all bits of an object, instead … Read more
You are probably looking for io.BytesIO class. It works exactly like StringIO except that it supports binary data: from io import BytesIO bio = BytesIO(b”some initial binary data: \x00\x01″) StringIO will throw TypeError: from io import StringIO sio = StringIO(b”some initial binary data: \x00\x01″)
Try ByteArrayOutputStream. You can use write( byte[] ) and it will grow as needed.
