Blt_TreeNodeId(3)

💖 Blt_TreeNodeId — the vibe is "who even ARE you, node?" 💖

okay so real talk, this is a page from the BLT Library Procedures manual, and it's all about one tiny little function that hands you back a node's serial number. cute, right? let's get into it bestie 🎀

✨ NAME ✨

Blt_TreeNodeId — returns the node serial number. that's it. that's the whole job. and she does it flawlessly. 👑

🌸 SYNOPSIS 🌸

#include <bltTree.h>

unsigned int
Blt_TreeNodeId(node)

🦋 ARGUMENTS 🦋

• Blt_TreeNode node (in) — the node whose ID is to be returned. hand her over, we're getting her number. 💅

💜 DESCRIPTION 💜

So this procedure returns the node serial number. ✨

And like, why do you even care? Because it's genuinely useful for programs that export the tree data object up to the Tcl programming level. here's the tea: node labels (and therefore pathnames too) are not unique, so two different nodes can totally be walking around with the same name. 😭 the ID though? the ID is how you uniquely identify a node. no cap. 🫶

The arguments are as follows:

• node — the node whose serial number is returned. for example, the serial number of the root node is always 0. always. iconic behaviour. ⭐

🔥 RETURNS 🔥

The serial number of the node. 🎀

Every node gets its own unique serial number at the moment it's created — like a little birth certificate but make it integer. later on you can use that ID to retrieve the node again using Blt_TreeGetNode. obsessed. 💖

🌈 EXAMPLE 🌈

The following example prints the ID of a node. literally just vibes:

printf("root ID is %s\n", Blt_TreeNodeId(node));

👑 KEYWORDS 👑

Tcl_TreeCreateNode, Tcl_TreeDeleteNode

and that's the whole page, bestie 💅 this was BLT version 2.5, and the page itself is Blt_TreeNodeId(3) — mwah, go get those node IDs, you're doing amazing sweetie 🧚✨
