Pipe() Support in FreeRTOS

Is Pipe() supported in FreeRTOS?
Please share the source code .

No - FreeRTOS is not that kind of OS. You can find a list of features here https://www.freertos.org/features.html and all the source code is on github http://github.com/freertos

Do you mean a pipe as a data stream that can be opened as a pseudo file (e.g. in Linux)?

One FreeRTOS feature that comes very close to a pipe is stream_buffer.c. It implements a circular buffer that can be used just like a pipe between two tasks. See for instance here

Thanks for your input!!
