Class Method Details

.adler32(string, adler) ⇒ Object

Calculates Alder-32 checksum for string, and returns updated value of adler. If string is omitted, it returns the Adler-32 initial value. If adler is omitted, it assumes that the initial value is given to adler.

FIXME: expression.

static VALUE
rb_zlib_adler32(argc, argv, klass)
int argc;

.crc32(string, adler) ⇒ Object

Calculates CRC checksum for string, and returns updated value of crc. If string is omitted, it returns the CRC initial value. If crc is omitted, it assumes that the initial value is given to crc.

FIXME: expression.
