50 * For convenience, the function calls 'json_object_put' for 'object'.
51 * Thus, in the case where 'object' should remain available after
52 * the function returns, the function 'json_object_get' shall be used.
54 * Calling this function is only forbidden during preinit.

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

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