void lxcpp::chdir ( const std::string & path )

void lxcpp::clearenv ( )

void lxcpp::clearenvExcept ( const std::vector< std::string > & names )

Clears the env variables except those listed.

There's a race condition - a moment when listed variables aren't set Function should be used only for setting up a new process.

Parameters

names names of the variables to keep

pid_t lxcpp::clone	(	int()(void )	function,
		void *	args,
		const int	flags
	)

Container * lxcpp::createContainer	(	const std::string &	name,
		const std::string &	rootPath,
		const std::string &	workPath
	)

bool lxcpp::isatty ( int fd )

Checks if a file descriptor is a terminal.

bool lxcpp::isMountPoint ( const std::string & path )

bool lxcpp::isMountPointShared ( const std::string & path )

Detect whether path is mounted as MS_SHARED.

Parses /proc/self/mountinfo

Parameters

path	mount point

Returns: is the mount point shared

void lxcpp::mount	(	const std::string &	source,
		const std::string &	target,
		const std::string &	filesystemtype,
		unsigned long	mountflags,
		const std::string &	data
	)

std::string lxcpp::nsToString ( const int ns )

int lxcpp::nullStdFDs ( )

Nullifies all standard file descriptors (stdin, stdout, stderr) replacing them with file descriptor to /dev/null.

Used to as a part of a process to detach a process from a control terminal.

This function has to be safe in regard to signal(7)

Returns: an error code in case of failure.

std::pair< int, std::string > lxcpp::openPty ( bool rawMode )

This function creates a new pair of virtual character devices using a pseudtoreminal interface.

It also configures as much as it can so the devices are immediately usable.

Parameters

rawMode Whether to set the terminal in the raw mode (termios(2))

Returns: file descriptor to the master device and the path/name of the pts slace device.

visible in ps tool).

Parameters

title A new tittle to be set

void lxcpp::setregid	(	const gid_t	rgid,
		const gid_t	egid
