XMCVTXMSTRINGTOCT(3)

💖 XmCvtXmStringToCT 💖

okay bestie, sit down, hydrate, because we're doing a library call today. This is XmCvtXmStringToCT, and no cap, she does exactly one thing and she does it gorgeously.

🎀 NAME 🎀

XmCvtXmStringToCT — a compound string function that converts a compound string to compound text. that's the vibe. that's the whole vibe. convert, bestie, convert. ✨

---

🦋 SYNOPSIS 🦋

#include <Xm/Xm.h>
char * XmCvtXmStringToCT(
XmString string);

yes the argument is on its own line, we respect her formatting, we do not touch her formatting 🫶

🌸 DESCRIPTION 🌸

So XmCvtXmStringToCT converts a compound string to a (char *) string in compound text format. Iconic behavior, honestly.

⚠️ Before you even THINK about calling this function, the application must call XtAppInitialize. Like, that's not optional, that's the entry fee. No XtAppInitialize, no function. periodt.

Now here's the tea 🍵: the converter uses the font list tag associated with a given compound string segment to select a compound text format for that segment. And a registry defines a mapping between font list tags and compound text encoding formats. So it's giving... matchmaking. Tags meet formats. love wins. 💅

The converter uses the following algorithm for each compound string segment:

1. If the compound string segment tag is mapped to XmFONTLIST_DEFAULT_TAG in the registry, the converter passes the text of the compound string segment to XmbTextListToTextProperty with an encoding style of XCompoundTextStyle and uses the resulting compound text for that segment. (the default-tag girlies stay winning ✨)
2. If the compound string segment tag is mapped to an MIT registered charset in the registry, the converter creates the compound text for that segment using the charset (from the registry) and the text of the compound string segment as defined in the X Consortium Standard Compound Text Encoding. (MIT registered charset, you're so valid 🎀)
3. If the compound string segment tag is mapped to a charset in the registry that is neither XmFONTLIST_DEFAULT_TAG nor an MIT registered charset, the converter creates the compound text for that segment using the charset (from the registry) and the text of the compound string segment as an "extended segment" with a variable number of octets per character. (extended segment? variable octets per character? she's complicated and we love her for it 💜)
4. If the compound string segment tag is not mapped in the registry, the result is implementation dependent. (aka: you're on your own, bestie. godspeed. 🙈)

• string — Specifies a compound string to be converted to compound text. that's the one you're feeding her. give her a good one. 🍓

💅 RETURN 💅

Returns a (char *) string in compound text format. This format is described in the X Consortium Standard Compound Text Encoding — go read it, it's giving scholarly.

The function allocates space to hold the returned string. The application is responsible for managing the allocated space. So like... she's not your mom. She handed you the memory, now you hold it. 🫶

The application can recover the allocated space by calling XtFree. (free your girl! let her go! closure! 🌈)

and that's the page, bestie!! this was XmCvtXmStringToCT from the library call manual (section 3, the library-call girlies), brought to you straight from the original footer — XmCvtXmStringToCT(library call), same title, same manual, and the date is just... the date on the tin, no extra deets given. 💖✨🦋 mwah, go call XtAppInitialize first, ily, bye!! 🎀👑💜
