Used to write a stream to a binary file. This file can be read into any programming environment that can read binary files (MATLAB, C, Python, ...). It can also be played back in GRC using a File Source. For example, if complex type is chosen, then the binary file will be full of float32s in IQIQIQ order. There is no meta data or anything else included with the binary data.


(R): Run-time adjustable

File (R)
Name of the file to open and write output to.
Specifies whether the output is buffered in memory. If the output is unbuffered, the data will be flushed to the file each time the work function is called. This can cause the flowgraph to run slow due to the time required to access the disk each time.
Append File
Whether or not to append to file, or create a new file each time.

Example Flowgraph

This flowgraph shows a File Sink which outputs text to the terminal (/dev/stdout).
