Beginning a command buffer recording operation

When we want to perform operations using hardware, we need to record them and submit them to a queue. Commands are recorded into command buffers. So when we want to record them, we need to begin a recording operation of a selected command buffer, effectively setting it in the recording state.

How to do it...

1. Take the handle of a command buffer, in which commands should be recorded, and store it in a variable of type VkCommandBuffer named command_buffer. Make sure the command buffer is allocated from a pool with a VK_COMMAND_POOL_CREATE_RESET_COMMAND_BUFFER_BIT flag set, or that it is in the initial state (it was reset).
2. Create a variable of a bit field type VkCommandBufferUsageFlags named usage and set the following bits depending on which conditions are met:
   1. If the command buffer will be submitted only once and then reset or re-recorded, set the VK_COMMAND_BUFFER_USAGE_ONE_TIME_SUBMIT_BIT bit.

    

   2. If it is the secondary command buffer and is considered...
