Types

ao_num64_t

typedef struct ao_num64_t ao_num64_t;

Represents a number.

ao_num64_wait_t

typedef struct ao_num64_wait_t ao_num64_wait_t;

Represents the waiting for a number match.

ao_num64_adjust_t

typedef uint64_t (* ao_num64_adjust_t)
(
    uint64_t value_old,
    void *   parameter
);

Represents a function to adjust a number value. The function takes the old value and an additional parameter and returns the new value.

ao_num64_match_t

typedef bool (* ao_num64_match_t)
(
    uint64_t value_old,
    uint64_t value_new,
    void *   parameter
);

Represents a function to check whether a specific number value is a match. The function takes both the old and the new value of a number as well as an additional parameter.
