globus_xio_tcp_driver_cntls 💅✨

okay bestie, this is the globus_xio_tcp_driver_cntls(3) manual page — Library Functions Manual vibes, and it's literally the TCP driver's entire personality in one page: every attr, every cntl, no gatekeeping. 🫶 We're doing this in five parts, so settle in, hydrate, and let's go.

🔥 Function Documentation 🔥

okay bestie, every single one of these is an overloaded member function — the docs say it's "provided for convenience" and it "differs from the above function only in what argument(s) it accepts." So like, same name, different lil argument lineup. classic 💅

💜 `GLOBUS_XIO_TCP_AFFECT_ATTR_DEFAULTS`

globus_result_t globus_xio_attr_cntl (attr , driver ,
    GLOBUS_XIO_TCP_AFFECT_ATTR_DEFAULTS , globus_bool_t affect_global)

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. Change the default attr values. ✨

Parameters

affect_global — If GLOBUS_TRUE, any future cntls on this attr will access the global default attr (which all new attrs are initialized from). The default is GLOBUS_FALSE.

⚠️ bestie listen to me on this one: this should only be used at the application level and there should only be one. There is no mutex protecting the global attr. This feature should not be abused. 😭

Some attrs make no sense to change globally, fr fr. Attrs that do include the tcp port range stuff, socket buffer sizes, etc.

🦋 `GLOBUS_XIO_TCP_GET_BACKLOG`

globus_result_t globus_xio_attr_cntl (attr , driver ,
    GLOBUS_XIO_TCP_GET_BACKLOG , int * listener_backlog_out)

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. Get the listener backlog on an attr.

Parameters

listener_backlog_out — The backlog will be stored here. 📥

🌸 `GLOBUS_XIO_TCP_GET_BLOCKING_IO`

globus_result_t globus_xio_attr_cntl (attr , driver ,
    GLOBUS_XIO_TCP_GET_BLOCKING_IO , globus_bool_t * use_blocking_io_out)

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. Get the blocking io status in use or in attr.

Parameters

use_blocking_io_out — The flag will be set here. GLOBUS_TRUE for enabled. 💖

🎀 `GLOBUS_XIO_TCP_GET_CONNECT_RANGE`

globus_result_t globus_xio_attr_cntl (attr , driver ,
    GLOBUS_XIO_TCP_GET_CONNECT_RANGE , int * connector_min_port_out, int *
    connector_max_port_out)

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. Get the tcp source port range on an attr.

Parameters

connector_min_port_out — The lower bound will be stored here.
connector_max_port_out — The upper bound will be stored here.

👑 `GLOBUS_XIO_TCP_GET_HANDLE`

globus_result_t globus_xio_attr_cntl (attr , driver ,
    GLOBUS_XIO_TCP_GET_HANDLE , globus_xio_system_socket_t * handle_out)

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. Get the tcp socket handle on an attr, handle, or server. 🔥

Parameters

handle_out — The tcp socket will be stored here. If none is set, GLOBUS_XIO_TCP_INVALID_HANDLE will be set.

🧚 `GLOBUS_XIO_TCP_GET_INTERFACE`

globus_result_t globus_xio_attr_cntl (attr , driver ,
    GLOBUS_XIO_TCP_GET_INTERFACE , char ** interface_out)

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. Get the interface on the attr.

Parameters

interface_out — A pointer to the interface will be stored here. If one is set, NULL will be passed back. Otherwise, the interface will be duplicated with strdup() and the user should call free() on it. 🫶

not me reminding you to free that thing — the docs literally say the user should call free() on it, so like, do that 💀

💅 `GLOBUS_XIO_TCP_GET_KEEPALIVE`

globus_result_t globus_xio_attr_cntl (attr , driver ,
    GLOBUS_XIO_TCP_GET_KEEPALIVE , globus_bool_t * keepalive_out)

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. Get the tcp keepalive flag.

Parameters

keepalive_out — The tcp keepalive flag will be stored here. 💫

🌈 `GLOBUS_XIO_TCP_GET_LINGER`

globus_result_t globus_xio_attr_cntl (attr , driver ,

    linger_time_out)

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. Get the tcp linger flag and time.

Parameters

linger_out — The linger flag will be stored here.
linger_time_out — The linger time will be set here.

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. Get the tcp port range on an attr.

Parameters

listener_min_port_out — The lower bound will be stored here.
listener_max_port_out — The upper bound will be stored here.

🍓 `GLOBUS_XIO_TCP_GET_NO_IPV6`

    GLOBUS_XIO_TCP_GET_NO_IPV6 , globus_bool_t * no_ipv6_out)

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. Get the no ipv6 flag on an attr.

Parameters

no_ipv6_out — The no ipv6 flag will be stored here. 🙈

🌟 `GLOBUS_XIO_TCP_GET_NODELAY`

globus_result_t globus_xio_attr_cntl (attr , driver ,
    GLOBUS_XIO_TCP_GET_NODELAY , globus_bool_t * nodelay_out)

If linger is set to true, then the close operation will block until the socket buffers are empty, or the linger_time has expired. If this is enabled, any data remaining after the linger time has expired, will be discarded. If this is disabled, close finishes immediately, but the OS will still attempt to transmit the remaining data. so she either waits patiently or leaves instantly, no in between 🌸

Parameters
