BIOSStream (  int32_t  descriptor,
uint32_t  flags = 0
) 
 

~BIOSStream (   )  [virtual]
 

Member Function Documentation

int32_t FileDescriptor (   )  const [virtual]
 

SValue Inspect (  const sptr< IBinder > &  caller,
const SValue &  which,
uint32_t  flags = 0
)  [virtual]
 

Probe binder for interface information.

Return interfaces implemented by this binder object that are requested by which. This is a composition of all interfaces, expressed as { descriptor -> binder } mappings, which are selected through which.

Much more information on Inspect() can be found at Binder Inspect() Details.

Reimplemented from BnInterface< IByteOutput >.

ssize_t ReadV (  const struct iovec *  vector,
ssize_t  count,
uint32_t  flags = 0
)  [virtual]
 

status_t Sync (   )  [virtual]
 

Make sure all data in the stream is written to its physical device.

Returns B_OK if the data is safely stored away, else an error code.

Implements IByteOutput.

ssize_t WriteV (  const struct iovec *  vector,
ssize_t  count,
uint32_t  flags = 0
)  [virtual]
