See more ULID/UUID Examples

Checks to see if a ULID is valid.

Important: Chilkat's ULID functionality was introduced in v9.5.0.94.

C++

#include <CkDateTime.h>

void ChilkatSample(void)
    {
    CkDateTime dt;

    //  A ULID must be exactly 26 chars in length,
    //  and is composed of the following chars: 0123456789ABCDEFGHJKMNPQRSTVWXYZ
    //  Note: The ULID alphabet excludes the letters I, L, O, and U

    //  Here's a valid ULID
    const char *ulid = "01GRGCH4J88RECEN4D4VK4F629";
    bool valid = dt.UlidValidate(ulid);
    std::cout << "valid: " << valid << "\r\n";

    //  Here's an invalid ULID
    ulid = "71GRGxx4Jr8RECEN4D4VK4F62!";
    valid = dt.UlidValidate(ulid);
    std::cout << "valid: " << valid << "\r\n";
    }
