struct send_params
{
char far *bufferPtr; // Pointer to send data
int bufferLength; // Number of bytes to send
int flags; // Blocking or no wait

This structure is defined in tcpip.h. The elements are used as follows:
bufferPtr
Pointer to data to be sent.
bufferLength
Number of bytes to be sent from bufferPtr.
flags

Set to one of following constants defined in tcpip.h:
MSG_BLOCKING: Sleep until data is transferred into the socket transmit queue
MSG_DONTWAIT: Return immediately after loading bytes into available transmit queue space
toPtr UDP only
The referenced structure is cast to a sockaddr_instructureprior to usage. The datagram destination IP address
and port number is specified here by caller.
tolengthPtr UDP only
The 16 bit value referenced by this pointer must be: sizeof(struct sockaddr_in)
