SYNOPSIS¶

#include <shishi.h>

int shishi_crc(Shishi * handle, const char * in, size_t inlen, char * out[4]);

ARGUMENTS¶

Shishi * handle

shishi handle as allocated by shishi_init().

const char * in

input character array of data to checksum.

size_t inlen

length of input character array of data to checksum.

char * out[4]
