array_crc32()

Calculates 32-bit CRC number.

Syntax

array_crc32(hnd);
array_crc32(hnd, pos);
array_crc32(hnd, pos, len);

hnd	Array handle.
pos	CRC data start position. Special values are:	(optional)
	0 - start position of array..
	Other: 1,2,3… (zero based numbering is used (1st position has number zero, 2nd number one etc…).
len	CRC data length value. Special values are:	(optional)
	-1 -end of array.
	Other: 1,2,3… (zero based numbering is used (1st position has number zero, 2nd number one etc…).
Return Value	Returns array size. Returned value is integer number.

hnd = array_new();
array_setdata(hnd, 0, 0x01, 0x02, 0x03, 0x04, 0x05);
result = array_crc32(hnd, 0, -1);
array_delete(hnd);

result:
