Hello, I was looking at the synchronization primitives in RIOT OS. I noticed that there is a mutex implementation, but I was unable to find a condition variable.
I am currently porting the TCP logic from the FreeBSD operating system to RIOT as part of the research work I am doing. I am implementing the "conn" API for TCP, and I need to be able to block the current thread until a packet is received, to implement some of the functions. I read the IPC implementation (msg.c), which also has a blocking API, and saw that it interacts with the scheduler manually in order to block and resume threads. Before I did the same thing for the conn API (or perhaps implement/contribute my own condition variable), I wanted to ask whether there are condition variables for RIOT, in case I was just looking in the wrong place. If not, I want to learn if there is another structured way to block a thread until an event, that I should use instead. Thanks, Sam Kumar
