Synchronous socket allocation function based on the specified socket type.
Created sockets are non-blocking and their possible types are either TCP or a UDP sockets. The maximum allowed number of TCP sockets is TCP_SOCK_MAX sockets while the maximum number of UDP sockets that can be created simultaneously is UDP_SOCK_MAX sockets.

[in] | u16Domain | Socket family. The only allowed value is AF_INET (IPv4.0) for TCP/UDP sockets. |
[in] | u8Type | Socket type. Allowed values are: |
[in] | u8Config | Used to specify the socket configuration. The following configuration values are defined:

This example demonstrates the use of the socket function to allocate the socket, returning the socket handler to be used for other socket operations. Socket creation is dependent on the socket type.
