Read() on OS4

On linux when you use read() function on stdin and you use fcntl(STDIN_FILENO, F_SETFL, flag); reading became non blocking and when you click on enter the read buffer is returned and the second time is returned -1 as EOF
Is there a way to do the same thing on AmigaOS4?

I've tried a client/server program and on OS4 (with newlib and clib2) there is no way to have the same behaviour

@afxgroup

Do you mean something like the bahvior described in the first answer of this question?

basically I was unable to set STDIN unlocked while a socket was on and so it was stuck on Read().. now it is implemented correctly on clib2 and all linux examples are working correclty
