Method: Zstdlib.crc32

Defined in:
ext/zstdlib_c/ruby/zlib-3.3/zstdlib.c

.crc32(*args) ⇒ Object

call-seq: Zstdlib.crc32(string, crc)

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+. If +string+ is an IO instance, reads from the IO until the IO returns nil and returns CRC checksum of all read data.

FIXME: expression.
