>Assumes 3rd argument points to an int containing the new timeout value
|
|
for this file descriptor. The unit is a "jiffy". Packets that are
|
|
already "in flight" will not be affected. The default value is set
|
|
on open() and is SG_DEFAULT_TIMEOUT (defined in sg.h). This default is
|
|
currently 1 minute and may not be long enough for formats. Negative
|
|
values will yield an EIO error.
|
|
This ioctl() is not relevant to the sg version 3 driver because timeouts
|
|
are specified explicitly for each command in the sg_io_hdr structure.
|
|
Only when the sg_header structure is used is the timeout inherited from
|
|
this value (help on a per file descriptor basis).</P
