NRF_MSG_DONTWAIT

#define NRF_MSG_DONTWAIT   0x40

#include <nrf_modem/include/nrf_socket.h>

Enables non-blocking operation for this specific function call.

If the operation blocks, the function returns immediately with -1 and sets errno to NRF_EAGAIN or NRF_EWOULDBLOCK. This flag has no effect if the socket is already set to non-blocking mode using nrf_fcntl. This flag is useful when an application wants to perform a single non-blocking operation on a socket that is otherwise in blocking mode. The default behavior is to follow the socket's blocking mode.
