XSaveContext(3)

🦋 XSaveContext(3) — XLIB FUNCTIONS 🦋

okay so bestie, this is the XSaveContext(3) page from the XLIB FUNCTIONS manual, and it’s giving associative look-up routine excellence. The cast: XSaveContext, XFindContext, XDeleteContext, and XUniqueContext. It’s literally the save/find/delete/make-a-new-context-type friend group 💅✨

✨ NAME ✨

XSaveContext, XFindContext, XDeleteContext, XUniqueContext — associative look-up routines. periodt 🎀

🌸 SYNTAX 🌸

int XSaveContext(Display *display, XID rid, XContext context, _Xconst char *data);

int XFindContext(Display *display, XID rid, XContext context, XPointer *data_return);

int XDeleteContext(Display *display, XID rid, XContext context);

XContext XUniqueContext(void);

🎀 ARGUMENTS 🎀

• context — specifies the context type to which the data belongs. the vibe category, iykyk 🫶
• data — specifies the data to be associated with the window and type. it’s the payload bestie.
• data_return — returns the data. yes, this is where the data comes back out 👑
• display — specifies the connection to the X server.
• rid — specifies the resource ID with which the data is associated.

💖 DESCRIPTION 💖

okay so here’s the tea. If an entry with the specified resource ID and type already exists, XSaveContext overrides it with the specified context. The XSaveContext function returns a nonzero error code if an error has occurred and zero otherwise. Possible errors are XCNOMEM (out of memory). no cap, that’s the whole error list for this one 😭

Because it is a return value, the data is a pointer. The XFindContext function returns a nonzero error code if an error has occurred and zero otherwise. Possible errors are XCNOENT (context-not-found). so if it’s not there, that’s the error vibe 💀

The XDeleteContext function deletes the entry for the given resource ID and type from the data structure. This function returns the same error codes that XFindContext returns if called with the same arguments. XDeleteContext does not free the data whose address was saved. so yeah, it removes the entry, but it does not free the data whose address was saved — important, bestie 🫶

The XUniqueContext function creates a unique context type that may be used in subsequent calls to XSaveContext. iconic behavior, honestly 🌟

X Version 11 • libX11 1.8.14 • XSaveContext(3) — that’s the footer source/version energy, and the date slot is lowkey absent in the original, so we’re not inventing one. bye bestie, slay your context look-ups 💖🎀✨
