CRC32 utility.

Function Documentation

ZFCrc32() [1/2]

zfflags ZFCrc32 ( const void * src, zfindex srcLen, zfflags prevResult = 0 )

extern

calculate CRC32, return ZFCrc32Invalid if failed

prevResult is used for continous calculation for performance, you may separate big buffer to small ones, and calculate separately

ZFCrc32() [2/2]

zfflags ZFCrc32 ( const ZFInput & callback, zfflags prevResult = (0) )

extern

calculate CRC32, return ZFCrc32Invalid if failed

prevResult is used for continous calculation for performance, you may separate big buffer to small ones, and calculate separately
