#include <Pipe.h>

Inherits noncopyable.

Public Member Functions
	Pipe (bool nonBlockingRead, bool nonBlockingWrite, bool closeOnExec)
std::size_t	read (void *buf, std::size_t count)
std::size_t	write (const void *buf, std::size_t count)

Detailed Description

Simple wrapper around pipes.

Constructor & Destructor Documentation

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

Constructor.

Parameters

nonBlockingRead	if true, reads on this pipe will be non-blocking
nonBlockingWrite	if true, writes on this pipe will be non-blocking
closeOnExec	if true, the close on exec flag is set on pipes file descriptors

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

FesaException

in 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

Exceptions

FesaException

in case of error
