Function Documentation
◆ rcl_node_get_default_options()
| RCL_PUBLIC rcl_node_options_t rcl_node_get_default_options | ( | void | ) |
Return the default node options in a rcl_node_options_t.
The default values are:
- allocator = rcl_get_default_allocator()
- use_global_arguments = true
- enable_rosout = true
- arguments = rcl_get_zero_initialized_arguments()
- rosout_qos = rcl_qos_profile_rosout_default
- Returns
- A structure with the default node options.

◆ rcl_node_options_copy()
| RCL_PUBLIC RCL_WARN_UNUSED rcl_ret_t rcl_node_options_copy | ( | const rcl_node_options_t * | options, |
| rcl_node_options_t * | options_out | ||
| ) |
Copy one options structure into another.

- Parameters
-
[in] options The structure to be copied. Its allocator is used to copy memory into the new structure. [out] options_out An options structure containing default values.
- Returns
- RCL_RET_OK if the structure was copied successfully, or
- RCL_RET_INVALID_ARGUMENT if any function arguments are invalid, or
- RCL_RET_BAD_ALLOC if allocating memory failed, or
- RCL_RET_ERROR if an unspecified error occurs.

◆ rcl_node_options_fini()
| RCL_PUBLIC RCL_WARN_UNUSED rcl_ret_t rcl_node_options_fini | ( | rcl_node_options_t * | options | ) |
Finalize the given node_options.
The given node_options must be non-NULL and valid, i.e. had rcl_node_get_default_options() called on it but not this function yet.

- Parameters
-
[in,out] options object to be finalized
- Returns
- RCL_RET_OK if setup is successful, or
- RCL_RET_INVALID_ARGUMENT if any arguments are invalid, or
- RCL_RET_ERROR if an unspecified error occurs.
