Description

detect

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

inbuf

input string for detecting

outbuf

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.
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

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 ("ìëíì¸ì", &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;
}
