50 * For convenience, the function calls 'json_object_put' for 'object'.

52 * the function returns, the function 'json_object_get' shall be used.
54 * Returns the count of clients that received the event.

117 * If 'group' is not NUL, the jobs queued with a same value (as the pointer value 'group')

119 * If 'timeout' is not 0, it represent the maximum execution time for the job in seconds.
