SYSCALL NUMBERING

Have a look in the sysroot at include/bits/syscall.h to determine the system call numbering.

Functions

void setSockAddr(sockaddr nativeSockAddr, I32 addrPtr)

Writes changes to a native sockaddr back to a wasm sockaddr. This is important in several networking syscalls that receive responses and modify arguments in place

void setSockLen(socklen_t nativeValue, I32 wasmPtr)

I32 s__socketcall(I32 call, I32 argsPtr)

When properly isolated, functions will run in their own network namespace, therefore we can be relatively comfortable passing some of the syscalls straight through.
