I would like to know: when programming in C using a socket (AF_UNIX) is there any limit (in bytes) when sending or receiving to or from a socket?

You can change the read and write buffers for each individual socket connection using
setsockopt(SO_SNDBUFandSO_RCVBUF).The default and maximum sizes are platform dependent.
Furthermore, if you provide a larger user-side buffer for each individual read e.g. with
recv.And if you use several
recvs in sequence, you can read an infinite amount of bytes over a connection, it’ll just take infinitely long.
