/**
* @brief Copy an array of Network Manager attributes
* @ingroup globus_net_manager_attr
* @details
* This function performs a deep copy of array of net_manager attributes.
* The new array will be stored in the pointer passed to by the dest_array
* parameter. It will contain all entries in the array passed as the
* src_array, ending with the value #GLOBUS_NET_MANAGER_NULL_ATTR.
*
* The caller must free the array stored in *dest_array by calling
* globus_net_manager_attr_array_destroy().
*
*
* @param[out] dest_array
* A pointer to an array of attributes to be allocated and initialized.
* @param[in] src_array
* An array of attributes to copy.
*
* @return
* On error, the dest_array is set to NULL and this function returns an error
* object. Otherwise, this function returns GLOBUS_SUCCESS.
