BUILD

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

FreeBSD

gmake

Other OS

METHODS

See api/yauid.h file

EXAMPLE

#include <stdio.h>
#include <yauid.h>

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;
}
