The TCP/IP system allows up to 16 different type calls to be outstanding for a particular socket descriptor. A different type call is a call that performs a different specific function. Following is a list of these different types of function calls:
Full-duplex socket support allows data to be sent and received on the same socket from different ECB programs without being blocked by the TPF system, the TCP/IP offload device, or the IP router.
If function calls from more than one ECB to the same socket are of the same type, blocking occurs. For example, if one ECB issues a read function call and another ECB issues a recv function call to the same socket, the second call is blocked until processing of the first function call is completed successfully.
