* Description:
* This function implements accept() for TCP/IP sockets. See the
* description of accept() for further information.
*
* Parameters:
* psock The listening TCP socket structure
* addr Receives the address of the connecting client
* addrlen Input: allocated size of 'addr', Return: returned size of 'addr'
* newconn The new, accepted TCP connection structure
*
* Returned Value:
* Returns zero (OK) on success or a negated errno value on failure.
* See the description of accept of the possible errno values in the
* description of accept().
*
* Assumptions:
* Network is locked.
