How to set line-buffer in Windows?
In Windows, the line buffering behavior can be adjusted for console output using the _setvbuf
function from the C runtime library. Here's an example of how you can set line buffering in a C program on Windows:
c#include <stdio.h>
int main() {
// Set line buffering for stdout
_setvbuf(stdout, NULL, _IOLBF, 4096); // 4096 is the buffer size in bytes
// Your program code here
return 0;
}
In this example, _setvbuf
is used to set line buffering for the standard output stream (stdout
). The function takes four arguments: the file stream (stdout
in this case), the buffer to be used (NULL for automatic allocation), the buffering mode (_IOLBF
for line buffering), and the buffer size in bytes (4096 in this example).
By setting the buffering mode to _IOLBF
, the standard output stream will be line-buffered, meaning that output will be flushed from the buffer and displayed on the console whenever a newline character ('\n'
) is encountered.
Compile and run your C program, and the line buffering behavior should be adjusted accordingly for console output.
Note that this method is specific to C programming on Windows using the C runtime library. It may not be applicable or directly usable in other programming languages or runtime environments.
