Function Documentation

rcl_logging_ret_t rcl_logging_get_logging_directory(rcutils_allocator_t allocator, char **directory)

Get the logging directory.

Uses various environment variables to construct a logging directory path.

Use $ROS_LOG_DIR if ROS_LOG_DIR is set and not empty. Otherwise, use $ROS_HOME/log, using ~/.ros for ROS_HOME if not set or if empty.

It also expands an initial ‘~’ to the current user’s home directory, and converts the path separator if necessary.

If successful, the directory C string should be deallocated using the given allocator when it is no longer needed.

Parameters

• allocator – [in] The allocator to use for memory allocation.

• directory – [out] The C string pointer at which to write the directory path. Only meaningful if the call is successful. Must not be nullptr and must point to nullptr.

Returns

RCL_LOGGING_RET_OK if successful, or

Returns

RCL_LOGGING_RET_INVALID_ARGUMENT if any arguments are invalid, or

Returns

RCL_LOGGING_RET_ERROR if an unspecified error occurs.
