C++ (Cpp) partialhash Examples

Example #1

File: diimage.c Project: NastyNoah/groovyarcade.groovymame

void device_image_interface::run_hash(void (*partialhash)(hash_collection &, const unsigned char *, unsigned long, const char *),
    hash_collection &hashes, const char *types)
{
    UINT32 size;
    UINT8 *buf = NULL;

    hashes.reset();
    size = (UINT32) length();

    buf = (UINT8*)malloc(size);
	memset(buf,0,size);

    /* read the file */
    fseek(0, SEEK_SET);
    fread(buf, size);

    if (partialhash)
        partialhash(hashes, buf, size, types);
    else
        hashes.compute(buf, size, types);

    /* cleanup */
    free(buf);
    fseek(0, SEEK_SET);
}

Example #2

File: image.c Project: broftkd/mess-cvs

static int run_hash(mess_image *image,
	void (*partialhash)(char *, const unsigned char *, unsigned long, unsigned int),
	char *dest, unsigned int hash_functions)
{
	UINT32 size;
	UINT8 *buf = NULL;

	*dest = '\0';
	size = (UINT32) image_length(image);

	buf = (UINT8 *) malloc(size);
	if (!buf)
		return FALSE;

	/* read the file */
	image_fseek(image, 0, SEEK_SET);
	image_fread(image, buf, size);

	if (partialhash)
		partialhash(dest, buf, size, hash_functions);
	else
		hash_compute(dest, buf, size, hash_functions);

	/* cleanup */
	if (buf)
		free(buf);
	image_fseek(image, 0, SEEK_SET);
	return TRUE;
}

Example #3

File: diimage.c Project: NastyNoah/groovyarcade.groovymame

void device_image_interface::device_compute_hash(hash_collection &hashes, const void *data, size_t length, const char *types) const
{
	/* retrieve the partial hash func */
	device_image_partialhash_func partialhash = get_partial_hash();

	/* compute the hash */
	if (partialhash)
		partialhash(hashes, (const unsigned char*)data, length, types);
	else
		hashes.compute(reinterpret_cast<const UINT8 *>(data), length, types);
}

Example #4

	hash_collection &hashes, const char *types)

	hashes.reset();
	size = (UINT32) length();

	buf.resize_and_clear(size);

	/* read the file */
	fseek(0, SEEK_SET);

	if (partialhash)
		partialhash(hashes, buf, size, types);
	else
		hashes.compute(buf, size, types);

	/* cleanup */
	fseek(0, SEEK_SET);
}
