Shellcode Compiler
A custom shellcode compiler for Binary Ninja
ssize_t recvfrom(int fd, void* buf, size_t n, int flags, struct sockaddr* addr, socklen_t* addrlen);

Reads n bytes from the socket fd, and places the result in buf. If addr is not NULL, fills in the address from which the data was received. Returns the number of bytes read, or the negation of the error code on error. It is possible for the number of bytes read to be smaller than the number of bytes requested.

Important If the system call is interrupted, this function will return -EINTR. This differs from most C runtimes, where -1 is returned with errno set to EINTR. As this runtime does not have errno, callers should check for -EINTR and a result less than zero in the error checking code.
