vkCreateShadersEXT

To create one or more shader objects, call:

VkResult vkCreateShadersEXT(
    VkDevice device,
    uint32_t createInfoCount,
    const VkShaderCreateInfoEXT* pCreateInfos,
    const VkAllocationCallbacks* pAllocator,
    VkShaderEXT* pShaders);

device is the logical device that creates the shader objects.
createInfoCount is the length of the pCreateInfos and pShaders arrays.
pCreateInfos is a pointer to an array of VkShaderCreateInfoEXT structures.
pAllocator controls host memory allocation as described in the Memory Allocation chapter.
pShaders is a pointer to an array of VkShaderEXT handles in which the resulting shader objects are returned.

When this function returns, whether or not it succeeds, it is guaranteed that every element of pShaders will have been overwritten by either VK_NULL_HANDLE or a valid VkShaderEXT handle.

This means that whenever shader creation fails, the application can determine which shader the returned error pertains to by locating the first VK_NULL_HANDLE element in pShaders. It also means that an application can reliably clean up from a failed call by iterating over the pShaders array and destroying every element that is not VK_NULL_HANDLE.
