NAME

       detect_handledata - Detecting character set and measuring accuracy of charset

SNOPSYS

       #include <chardet.h>

       short chardet_handledata (Detect ** handle, const char * inbuf, DetectObj ** outbuf);

DESCRIPTION

       Storing charset and accuracy of inbuf to outbuf

       handle
              Detect handle resource that allocated by detect_init api.

       inbuf
              input string for detecting

       outbuf
              Stroing inforamtion of inbuf . The structure of outbuf is follows.

                   typedef struct DetectObject {
                        char * encoding;
                        float confidence;
                   } DetectObj;

              The  outbuf variable must be initialized by detect_obj_init API before calling this
              detect api.

RETURN VALUES

       Returns following condition as case by case.

       CHARDET_SUCCESS
              Detecting success

       CHARDET_NO_RESULT
              Detection failure

       CHARDET_NULL_OBJECT
              Don't initializing outbuf with chardet_obj_init

       CHARDET_OUT_OF_MEMORY
              Occuring out of memory at internal API

                      return CHARDET_MEM_ALLOCATED_FAIL;
                 }

                                     "with detect_obj_init API\n");
                           return CHARDET_NULL_OBJECT;
                 }

                 printf ("encoding: %s, confidence: %f\n", obj->encoding, obj->confidence);
                 detect_obj_free (&obj);
            }
            detect_destroy (&d);

           return 0;
