Form is [be|le]:[s|u]bits/storagebits[>>shift]. be or le specifies big or little endian. s or u specifies if signed (2's complement) or unsigned. bits is the number of bits of data and storagebits is the space (after padding) that it occupies in the buffer. shift if specified, is the shift that needs to be applied prior to masking out unused bits. Some devices put their data in the middle of the transferred elements with additional information on both sides. Note that some devices will have additional information in the unused bits so to get a clean value, the bits value must be used to mask the buffer output value appropriately. The storagebits value also specifies the data alignment. So s48/64>>2 will be a signed 48 bit integer stored in a 64 bit location aligned to a 64 bit boundary. To obtain the clean value, shift right 2 and apply a mask to zero the top 16 bits of the result. For other storage combinations this attribute will be extended appropriately.

Thus for user-space to establish the full layout these must be used in conjunction with all _en attributes to establish which channels are present, and the relevant _type attributes to establish the data storage format.

Poll will block until the watermark is reached. Blocking read will wait until the minimum between the requested read amount or the low water mark is available. Non-blocking read will retrieve the available samples from the buffer even if there are less samples then watermark level. This allows the application to block on poll with a timeout and read the available samples after the timeout expires and thus have a maximum delay guarantee.
