void* pw_buffer::user_data

user data attached to the buffer

uint64_t pw_buffer::size

This field is set by the user and the sum of all queued buffer is returned in the time info.

For audio, it is advised to use the number of samples in the buffer for this field.

uint64_t pw_buffer::requested

For playback streams, this field contains the suggested amount of data to provide.

For audio streams this will be the amount of samples required by the resampler. This field is 0 when no suggestion is provided. Since 0.3.49
