detect_handledata - Detecting character set and measuring accuracy of charset
#include <chardet.h>
short chardet_handledata (Detect ** handle, const char * inbuf, DetectObj ** outbuf);
Storing charset and accuracy of inbuf to outbuf
typedef struct DetectObject { char * encoding; float confidence; } DetectObj;
The outbuf variable must be initialized by detect_obj_init API before calling this detect api.
Returns following condition as case by case.
#include <chardet.h> int main (void) { Detect * d; DetectObj * obj; int i, arrayNum; char *str[] = { "this is ascii", "이건 euc-kr 입니다." }; arrayNum = sizeof (str) / sizeof (str[0]); if ( (d = detect_init ()) == NULL ) { fprintf (stderr, "chardet handle initialize failed\n"); return CHARDET_MEM_ALLOCATED_FAIL; } for ( i=0; i<arrayNum; i++ ) { detect_reset (&d); if ( (obj = detect_obj_init ()) == NULL ) { fprintf (stderr, "Memory Allocation failed\n"); return CHARDET_MEM_ALLOCATED_FAIL; } switch (detect_handledata (&d, "안녕하세요", &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; } printf ("encoding: %s, confidence: %f\n", obj->encoding, obj->confidence); detect_obj_free (&obj); } detect_destroy (&d);
return 0; }
