Detailed Description


Function Documentation

t38_terminal_state_t* t38_terminal_init ( t38_terminal_state_t *  s,
int  calling_party,
t38_tx_packet_handler_t *  tx_packet_handler,
void *  tx_packet_user_data 
)

Initialise a termination mode T.38 context.

Parameters:
s The T.38 context.
calling_party TRUE if the context is for a calling party. FALSE if the context is for an answering party.
tx_packet_handler A callback routine to encapsulate and transmit T.38 packets.
tx_packet_user_data An opaque pointer passed to the tx_packet_handler routine.
Returns:
A pointer to the termination mode T.38 context, or NULL if there was a problem.
