Declaration
int sock_isnonblocking(socket_t so);Return Value
0 - socket will block. 1 - socket will not block.
Discussion
Returns whether or not the socket is non-blocking. In the context of this KPI, non-blocking means that functions to perform operations on a socket will not wait for completion.
To enable or disable blocking, use the FIONBIO ioctl. The parameter is an int. If the int is zero, the socket will block. If the parameter is non-zero, the socket will not block.
