Signature

get_socket_descriptor( : : Socket : SocketDescriptor)

Herror T_get_socket_descriptor(const Htuple Socket, Htuple* SocketDescriptor)

void GetSocketDescriptor(const HTuple& Socket, HTuple* SocketDescriptor)

Hlong HSocket::GetSocketDescriptor() const

static void HOperatorSet.GetSocketDescriptor(HTuple socket, out HTuple socketDescriptor)

int HSocket.GetSocketDescriptor()

def get_socket_descriptor(socket: HHandle) -> int

Description

get_socket_descriptorget_socket_descriptorGetSocketDescriptorGetSocketDescriptorget_socket_descriptor returns the socket descriptor used by the operating system for the socket connection that is passed in SocketSocketSocketsocketsocket. The socket descriptor can be used in operating system calls such as select, read, write, recv, or send.

Execution Information

• Multithreading type: reentrant (runs in parallel with non-exclusive operators).
• Multithreading scope: global (may be called from any thread).
• Processed without parallelization.
