detect_obj_free(3)

💖 detect_obj_free(3) 💖

okay bestie, so this is a page from the Library Functions Manual — yes it says detect_obj_free up top but the actual function name lives in NAME, classic manpage behavior, we don't question it, we just vibe 🦋

---

✨ NAME ✨

chardet_obj_free — free DetectObject structure

---

✨ SNOPSIS ✨

(not me spelling it like that, that's literally what the page says, i don't make the rules 💅)

#include <chardet.h>
void chardet_obj_free (DetectObj **);

---

✨ DESCRIPTION ✨

so basically this frees the resource of the DetectObject structure — the one that got allocated by the chardet_obj_init api in the first place. it's the cleanup bestie. the "okay we're done here, release the memory" moment. 🧹✨

---

✨ RETURN VALUE ✨

void — it gives you nothing back, and honestly? iconic. no cap, it just does the thing and leaves. 👑

---

✨ EXAMPLE ✨

here's the whole thing fr fr, verbatim, no edits:

#include <chardet.h>

int main (void) {
     DetectObj *obj;

     if ( (obj = detect_obj_init ()) == NULL ) {
          fprintf (stderr, "Memory Allocation failed\n");
          return CHARDET_MEM_ALLOCATED_FAIL;
     }

     switch (detect ("¾È³çÇϼ¼¿ä", &obj)) {
          case CHARDET_OUT_OF_MEMORY :
               fprintf (stderr, "On handle processing, occured out of memory\n");
               detect_obj_free (&obj);
               return CHARDET_OUT_OF_MEMORY;
          case CHARDET_NULL_OBJECT :
               fprintf (stderr,
                         "2st argument of chardet() is must memory allocation "
                         "with detect_obj_init API\n");
               return CHARDET_NULL_OBJECT;
     }

     # check support obj->bom with CHARDET_BOM_CHECK constant
     printf ("encoding: %s, confidence: %f, exists bom: %d\n", obj->encoding, obj->confidence, obj->bom);
     detect_obj_free (&obj);

    return 0;
}

see how it calls detect_obj_free (&obj); when things go sideways and at the end when everything slays? that's the whole point. clean up after yourself, always. 🌸

lowkey important reminder: this frees a DetectObject that chardet_obj_init allocated. that's the whole lore. don't overthink it, just free your objects and live your truth. ✨
