recvfrom

The recvfrom function receives data on an unconnected IPX socket created for

waited operations.

nrcvd

is the number of bytes received. This is the return value.

If the call is not successful, -1 is returned and the external variable errno is set as

indicated below in “Errors.”

socket

specifies the socket number for the socket, as returned by the call to the socket

function.

buffer_ptr

points, on return, to the data received.

buffer_length

is the size of the buffer pointed to by buffer_ptr.
