int

💖 DESCRIPTION 💖

So bestie, sctp_generic_recvmsg() is the true system call used by the sctp_recvmsg(3) function call. She’s more efficient since she is a true system call, but she’s also specific to FreeBSD — and the manual is very clear that she can be expected not to be present on any other operating system. 🦋

She’s FreeBSD-only, bestie. The original literally says she can be expected not to be present on any other operating system. No cap. 💅

For detailed usage, please see the sctp_recvmsg(3) function call. iykyk 👑

🦋 RETURN VALUES 🦋

The call returns the number of bytes read on success and -1 upon failure. Periodt. 💀
