Returns
the name of the class

Implements StreamBase.

◆ peek()

DLLLOCAL int64 PipeInputStream::peek ( ExceptionSink xsink)
overridevirtual

Peeks the next byte from the input stream.

Parameters
xsinkthe exception sink
Returns

Implements InputStream.

◆ read()

DLLLOCAL int64 PipeInputStream::read ( void *  ptr,
int64  limit,
ExceptionSink xsink 
)
overridevirtual

Reads up to `limit` bytes from the input stream.

Parameters
ptrthe destination buffer to read data into
limitthe maximum number of bytes to read, must be > 0
xsinkthe exception sink
Returns
the number of bytes read, 0 indicates the end of the stream

Implements InputStream.
