Functions

void eosio::check(
    bool pred,
    const char * msg
)

Assert if the predicate fails and use the supplied message.

Example:

eosio::check(a == b, "a does not equal b");

void eosio::check(
    bool pred,
    const std::string & msg
)

Assert if the predicate fails and use the supplied message.

Example:

eosio::check(a == b, "a does not equal b");

void eosio::check(
    bool pred,
    std::string && msg
)

Assert if the predicate fails and use the supplied message.

Example:

eosio::check(a == b, "a does not equal b");

void eosio::check(
    bool pred,
    const char * msg,
    size_t n
)

Assert if the predicate fails and use a subset of the supplied message.

Example:

const char* msg = "a does not equal b b does not equal a";
eosio::check(a == b, "a does not equal b", 18);

void eosio::check(
    bool pred,
    const std::string & msg,
    size_t n
)

Assert if the predicate fails and use a subset of the supplied message.

Example:

std::string msg = "a does not equal b b does not equal a";
eosio::check(a == b, msg, 18);

void eosio::check(
    bool pred,
    uint64_t code
)

Assert if the predicate fails and use the supplied error code.

Example:

eosio::check(a == b, 13);
