socket_get_info

The socket_get_info function returns the sockaddr data structure and the

sockaddr length received after a recvfrom_nw call.

error

is the return value. If the call is successful, the size of the sockaddr data structure

is returned. If the call is not successful, -1 is returned. If the call failed, the external

variable errno is set as indicated below in “Errors.”

socket

is an input parameter: the socket specified in the prior recvfrom_nw call.

sockaddr_buffer

is a character pointer to the sockaddr_in or sockaddr_nv data structure

returned by the call.

buflen

as an input parameter, is the size of sockaddr_in_buffer or

sockaddr_nv_buffer in bytes. Maximum value is 80 bytes.

Example

See Example on page 5-39 for recvfrom_nw.
