Are read/write on pipes thread safe.

Hello,

I am using a pipe to communicate two threads and I am not sure on whether I must protect the read and write operation with a mutex or the kernel garantee that thsese operations are thread-safe.

Thank you in advance.

you need to give us more detail. One single read and write operation on a pipe is safe, parallel reading and writing should be checked, but it depends on how did you compile your app.

Muliple writers with a mutex to protect data consistency and a single reader without mutex.
But if a single reader and single writer works I assume the above scenario is correct.

Thank you!
