int eth_is_address(const char *addr)

Checks whether the addr is an address or not.

Parameters

addr – [in] Target address to check.

Returns

1 if addr is valid, -1 otherwise.

int eth_is_checksum_address(const char *addr)

Checks whether the addr is a valid checksum address or not.

#include <stdio.h>
#include <ethc/address.h>

int main(void) {
  const char *addr0 = "0x1B9F402eaE18F10B1fD20d15b0c91EA64e3Ae1Ed";
  const char *addr1 = "0x51fabbb96a297368f0bf2dedffa285a921f7d613";

  printf("addr0 is checksum address: %d\n", eth_is_checksum_address(addr0));
  printf("addr1 is checksum address: %d\n", eth_is_checksum_address(addr1));

  return 0
}

Parameters

addr – [in] Target address to check.

Returns

1 if addr is valid, -1 otherwise.

int eth_to_checksum_address(char *addr)

Converts given addr to checksum address.

#include <stdio.h>

  printf("after checksumm: %s\n", addr);

  return 0
}

Parameters

addr – [out] Target address.

Returns

1 on success, -1 otherwise.
