## Name

Loading… please wait.

## C Specification

The `VkBaseInStructure` structure is defined as:

    // Provided by VK_VERSION_1_0
    typedef struct VkBaseInStructure {
        VkStructureType                    sType;
        const struct VkBaseInStructure*    pNext;
    } VkBaseInStructure;

## Members

- `sType` is the structure type of the structure being iterated through.

- `pNext` is `NULL` or a pointer to the next structure in a structure chain.

## Description

`VkBaseInStructure` can be used to facilitate iterating through a read-only structure pointer chain.
