stdin

Disclaimer: The author of the question has an average knowledge of Erlang and a basic knowledge of C. I am reading the Interoperability Tutorial User Guide now. I have successfully compiled the complex.c example and it works with the Erlang Port without any problems. However, I would like to understand how the actual C code works. I understand it in general: in the example it reads 2 bytes from the standard input and checks the first byte. Depending on the first byte it calls either foo or bar function. This is the limit of my understanding of it right now. So, if we take both erl_comm.c : /*

I am essentially trying to write a console interface with input and output for an embedded python script. Following the instructions here , I was able to capture stdout: Py_Initialize(); PyRun_SimpleString("\ class StdoutCatcher:\n\ def __init__(self):\n\ self.data = ''\n\ def write(self, stuff):\n\ self.data = self.data + stuff\n\ import sys\n\ sys.stdout = StdoutCatcher()"); PyRun_SimpleString("some script"); PyObject *sysmodule; PyObject *pystdout; PyObject *pystdoutdata; char *string; sysmodule = PyImport_ImportModule("sys"); pystdout = PyObject_GetAttrString(sysmodule, "stdout");

I'm trying to pipe a string into a program's STDIN without any trailing linefeeds (unless that string itself actually ends in a linefeed). I tried googling around, but I only found people trying to print to the console without a trailing linefeed, in which case Write-Host takes a parameter -NoNewLine . However, to pipe it on to another program, I need Write-Output or similar which doesn't have such a parameter. Now it seems like Write-Output isn't even the problem: Z:\> (Write-Output "abc").Length 3 But as soon as I pipe it to another program and read the string there, I get an additional

Im trying to send a lot of desktop captured images to an encoders (FFmpeg) stdin. The following code example works. the CaptureScreen() function provides an image in 5-10 ms. If I save the image in a MemoryStream it takes almost no time. But I can only save 1 image every 45 ms to proc.StandardInput.BaseStream. public void Start(string bitrate, string buffer, string fps, string rtmp, string resolution, string preset) { proc.StartInfo.FileName = myPath + "\\ffmpeg.exe"; proc.StartInfo.Arguments = "-f image2pipe -i pipe:.bmp -vcodec libx264 -preset " + preset + " -maxrate " + bitrate + "k
