Function Documentation

◆ sigint_handler()

void sigint_handler ( int  dummy)

SIGINT handler to ensure the socket is closed on termination.

Parameters
[in]dummyDummy argument.

◆ tcp_listen()

int tcp_listen ( int  port_in)

Begin listening for incoming TCP connections.

Parameters
[in]portPort to listen over

◆ tcp_recv()

int tcp_recv ( void *  buf,
int  count,
MDI_Datatype  datatype,
MDI_Comm  comm,
int  msg_flag 
)

Receive data through an MDI connection, using TCP.

Parameters
[in]bufPointer to the buffer where the received data will be stored.
[in]countNumber of values (integers, double precision floats, characters, etc.) to be received.
[in]datatypeMDI handle (MDI_INT, MDI_DOUBLE, MDI_CHAR, etc.) corresponding to the type of data to be received.
[in]commMDI communicator associated with the connection to the sending code.
[in]msg_flagType of role this data has within a message. 0: Not part of a message. 1: The header of a message. 2: The body (data) of a message.

◆ tcp_request_connection()

int tcp_request_connection ( int  port_in,
char *  hostname_ptr 
)

Request a connection over TCP.

Parameters
[in]portPort over which the driver is listening
[in]hostname_ptrHostname of the driver

◆ tcp_send()

int tcp_send ( const void *  buf,
int  count,
MDI_Datatype  datatype,
MDI_Comm  comm,
int  msg_flag 
)

Send data through an MDI connection, using TCP.

Parameters
[in]bufPointer to the data to be sent.
[in]countNumber of values (integers, double precision floats, characters, etc.) to be sent.
[in]datatypeMDI handle (MDI_INT, MDI_DOUBLE, MDI_CHAR, etc.) corresponding to the type of data to be sent.
[in]commMDI communicator associated with the intended recipient code.
[in]msg_flagType of role this data has within a message. 0: Not part of a message. 1: The header of a message. 2: The body (data) of a message.
