DTDTSSETDATATYPE(3)

🎀 NAME 🎀

DtDtsSetDataType — sets the data type of a directory, bestie. Yes, the whole function is literally “directory, but make it typed” ✨ This is the DtDtsSetDataType library call page, and we’re getting into it.

✨ SYNOPSIS ✨

#include &<Dt/Dts.h>
char *DtDtsSetDataType(
const char *dirpath,
const char *datatype,
const int override);

💅 DESCRIPTION 💅

okay so DtDtsSetDataType sets the data type of a directory. The way it does this? By adding a file named with a leading dot to the directory. Iconic behavior, no cap.

• dirpath — a pathname of the directory.
• datatype — a data type.
• override — if the value is already set, DtDtsSetDataType does not change the value unless override is set to True.

Lowkey important: that True with a capital T is doing the actual work. If the value is already set and override isn’t True, it stays exactly where it is 💅

🌈 RETURN VALUE 🌈

Upon successful completion, the DtDtsSetDataType function returns a pointer to a data type string, or NULL if it was unable to set or retrieve the data type. That’s the whole vibe check 🫶

🦋 APPLICATION USAGE 🦋

Directories can have data types associated with them, just as regular files can. For example, a file manager may choose to alter the appearance of the directory’s icon based on this data type, or a system may use a directory of files as an means of supporting a complex form of data, such as a compund document. Not me explaining directory glow-ups 😭✨
