tnet_msg_poll

#include <net_config.h>

BOOL tnet_msg_poll (
    U8 session);        /* Telnet Session handle. */

The tnet_msg_poll function polls the upper-layer user application for unsolicited messages. The Telnet session handle parameter session can be used to identify the remote host when many Telnet connections are active at the same time.

• __TRUE = the upper-layer user application has a pending message to send. A telnet callback function is called immediately to get the message.
• __FALSE = no pending message to send.
