=====

A decentralized unique ID generator (int64)

## DESCRIPTION

ID generation at a node should not require coordination with other nodes. Ids should be roughly time-ordered when sorted lexicographically.

## BUILD

Build succeeded on FreeBSD, Mac OS X and Linux. Use GNU Make

##### FreeBSD

```sh

gmake

```

##### Other OS

```sh

make

```

## METHODS

See api/yauid.h file

## EXAMPLE

```c

#include 

#include 

int main(int argc, const char * argv[])

{

    yauid* yaobj = yauid_init("lock.yauid", NULL);

    

    if(yaobj == NULL)

    {

        printf("Can't create object\n");

        return 0;

    }

    

    yauid_set_node_id(yaobj, 12);

    

    hkey_t key = yauid_get_key(yaobj);

    

    printf("yauid: %"PRId64"; time: %ld; node id: %ld; inc: %ld \n", key,

                yauid_get_timestamp(key), yauid_get_node_id(key), yauid_get_inc_id(key));

    

    yauid_destroy(yaobj);

    

    return 0;

}

```
