💜 DETAILED DESCRIPTION 💜

Globus XIO GRIDFTP Client Driver. that's it, that's the thesis statement.

🎀 Handles 🎀

so here's the tea: an XIO handle with the gridftp client driver can be created with globus_xio_handle_create(). iconic.

the GridFTP client driver makes use of the globus ftp client library. when you call globus_xio_register_open(), it creates a new ftp client handle (unless one is already set on the attr you passed in — no need to double up, bestie), and it establishes the connection with the GridFTP server. ✨

and the contact string? it must contain the scheme, the host name, and the resource. optionally it might also contain the port and the subject. like, those two are the little bonus stickers on top, yk? 🎀

when the XIO handle is closed, the GridFTP driver will destroy its internal resources and the ftp client handle (unless, again, that handle was set on an attr — in which case hands off, it's not yours to destroy 💅).

📖 Reading/Writing 📖

globus_xio_register_read() enforces that the waitforbytes parameter should be one. yep. one. just one. when multiple TCP streams are used between the client and the server, data might not be delivered in order — it's not being rude, it's just built different 🦋. globus_xio_data_descriptor_cntl() can be used to get the offset of the data.

globus_xio_register_write() does not enforce any restriction on the waitforbytes parameter. go off, honestly.

in any case, when an error or EOF occurs before the waitforbytes request has been met, the outgoing nbytes is set to the amount of data actually read/written before the error or EOF occurred. so you always know how far you got before it went sideways. 🫶
