Description:
|
||||
Description of the scan element data storage within the buffer
|
||||
and hence the form in which it is read from user-space.
|

Form is [s|u]bits/storagebits[>>shift]. s or u specifies if
|
||||
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
