Read from socket
- by Alberto
I need to read from an AF_UNIX socket to a buffer using the function read from C, but I don't know the buffer size.
I think the best way is to read N bytes until the read returns 0 (no more writers in the socket). Is this correct? Is there a way to guess the size of the buffer being written on the socket?
I was thinking that a socket is a special file. Opening the file in binary mode and getting the size would help me in knowing the correct size to give to the buffer?
I'm a very new to C, so please keep that in mind.
