detect(3) Library Functions Manual detect(3)

NAME

detect - Detecting character set and measuring accuracy of charset

SYNOPSIS

#include <chardet.h>

short chardet (char * inbuf, DetectObj ** outbuf);

DESCRIPTION

Storing charset and accuracy of inbuf to outbuf


input string for detecting


Storing information 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 VALUE

Returns following condition as case by case.


Detecting success


Detection failure


Don't initializing outbuf with chardet_obj_init


Occuring out of memory at internal API

EXAMPLE

#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 ("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);

return 0; }
