/** PCM hardware configuration space container
*
* snd_pcm_hw_params_t is an opaque structure which contains a set of possible
* PCM hardware configurations. For example, a given instance might include a
* range of buffer sizes, a range of period sizes, and a set of several sample
* formats. Some subset of all possible combinations these sets may be valid,
* but not necessarily any combination will be valid.
*
* When a parameter is set or restricted using a snd_pcm_hw_params_set*
* function, all of the other ranges will be updated to exclude as many
* impossible configurations as possible. Attempting to set a parameter
* outside of its acceptable range will result in the function failing
* and an error code being returned.
