vkCmdBindShadersEXT

Once shader objects have been created, they can be bound to the command buffer using the command:

void vkCmdBindShadersEXT(
    VkCommandBuffer commandBuffer,
    uint32_t stageCount,
    const VkShaderStageFlagBits* pStages,
    const VkShaderEXT* pShaders);

• commandBuffer is the command buffer that the shader object will be bound to.
• stageCount is the length of the pStages and pShaders arrays.
• pStages is a pointer to an array of VkShaderStageFlagBits values specifying one stage per array index that is affected by the corresponding value in the pShaders array.
• pShaders is a pointer to an array of VkShaderEXT handles and/or VK_NULL_HANDLE values describing the shader binding operations to be performed on each stage in pStages.

When binding linked shaders, an application may bind them in any combination of one or more calls to vkCmdBindShadersEXT (i.e., shaders that were created linked together do not need to be bound in the same vkCmdBindShadersEXT call).

Any shader object bound to a particular stage may be unbound by setting its value in pShaders to VK_NULL_HANDLE. If pShaders is NULL, vkCmdBindShadersEXT behaves as if pShaders was an array of stageCount VK_NULL_HANDLE values (i.e., any shaders bound to the stages specified in pStages are unbound).
