fesa::Pipe::Pipe ( bool  nonBlockingRead,
bool  nonBlockingWrite,
bool  closeOnExec 
)

Member Function Documentation

std::size_t fesa::Pipe::read ( void *  buf,
std::size_t  count 
)

Reads from the pipe up to count bytes. Result is written to buf. If the pipe is non-blocking and the read operation would block, then this immediately returns 0.

Returns
the number of bytes actually read
Exceptions
FesaExceptionin case of error
std::size_t fesa::Pipe::write ( const void *  buf,
std::size_t  count 
)

Writes to the pipe up to count bytes from buf. If the pipe is non-blocking and the write operation would block, then this immediately returns 0.

Returns
the number of bytes actually read
