Member Function Documentation

void Pipe::close (   )

Close the pipe.

void Pipe::closeRead (   )

Close the read stream of the pipe.

void Pipe::closeWrite (   )

Close the write stream of the pipe.

int Pipe::create (  bool  readPipe = true  )

Create the pipe descriptors. Return 0 on success. Parameters: readPipe  Specify if the current process uses it for read. A false value means the process uses it to write.

long Pipe::getReadHandle (   )

Get the handle to use to read from the pipe.

long Pipe::getWriteHandle (   )

Get the handle used to write to the pipe.

void Pipe::inverted (  Pipe &  pipe  )

Invert the current pipe on another instance of the class. The input will be used as output and viceversa. Parameters: pipe  The pipe where write.

bool Pipe::pipeTerminated (   )

int Pipe::read (  char *  buffer, u_long  len, u_long *  nbr )  [virtual]

Read from the pipe. Parameters: buffer  Where write. len  Buffer size. nbr  Get how many bytes were read. Reimplemented from Stream.

int Pipe::write (  const char *  buffer, u_long  len, u_long *  nbw )  [virtual]

Write from the pipe. Parameters: buffer  What write. len  Buffer size. nbr  Get how many bytes were really written. Reimplemented from Stream.
