pub unsafe extern "C" fn OH_ArkUI_GetNavDestinationNameByIndex(
    node: ArkUI_NodeHandle,

Available on crate feature api-12 only.

Based on the given index value, obtain the page name of the corresponding position in the navigation stack where the node is located. Index values are counted from 0, with 0 being the bottom of the stack.

Arguments

• node - The node.

• index - The index of the NavDestination in the stack is queried.

• buffer - The buffer to which NavDestination index writes to the memory, memory space needs to be allocated by the developer.

• bufferSize - The buffer size

• writeLength - Indicates the string length actually written to the buffer when returning [ARKUI_ERROR_CODE_NO_ERROR]. Indicates the minimum buffer size that can accommodate the target when [ARKUI_ERROR_CODE_BUFFER_SIZE_ERROR] is returned.

Returns

• The error code. [ARKUI_ERROR_CODE_NO_ERROR] if the operation is successful. [ARKUI_ERROR_CODE_PARAM_INVALID] if the node, buffer or writeLength is null. [ARKUI_ERROR_CODE_NODE_INDEX_INVALID] if index is an invalid value. [ARKUI_ERROR_CODE_GET_INFO_FAILED] if query information failed, this may be because the node is not in Navigation. [ARKUI_ERROR_CODE_BUFFER_SIZE_ERROR] If the buffer size is less than the minimum buffer size.
