Detailed Description

Platform independent class for creating processes.

Constructor & Destructor Documentation

_ExProcess::_ExProcess	(	const comms::cStr &	command,
		const comms::cStr &	path = comms::cStr(),
		std::function< void(const char *bytes, size_t n)>	read_stdout = nullptr,
		std::function< void(const char *bytes, size_t n)>	read_stderr = nullptr,
		bool	open_stdin = false,
		size_t	buffer_size = 131072
	)

Note on Windows: it seems not possible to specify which pipes to redirect. Thus, at the moment, if read_stdout==nullptr, read_stderr==nullptr and open_stdin==false, the stdout, stderr and stdin are sent to the parent process instead.

_ExProcess::_ExProcess	(	std::function< void()>	function,
		std::function< void(const char *bytes, size_t n)>	read_stdout = nullptr,
		std::function< void(const char *bytes, size_t n)>	read_stderr = nullptr,
		bool	open_stdin = false,
		size_t	buffer_size = 131072
	)

Supported on Unix-like systems only.

Member Function Documentation

void _ExProcess::close_stdin

(

)

Close stdin. If the process takes parameters from stdin, use this to notify that all parameters have been sent.

int _ExProcess::get_exit_status

(

)

Wait until process is finished, and return exit status.

_ExProcess::id_type _ExProcess::get_id

(

)

Get the process id of the started process.

void _ExProcess::kill

(

bool

force = false

)

Kill the process. force=true is only supported on Unix-like systems.

Referenced by kill().

void _ExProcess::kill ( id_type  id, bool  force = false  )

static

Kill a given process id. Use kill(bool force) instead if possible. force=true is only supported on Unix-like systems.

References kill().

bool _ExProcess::write	(	const char *	bytes,
		size_t	n
	)

Write to stdin.

bool _ExProcess::write

(

const std::string &

data

)

Write to stdin. Convenience function using write(const char *, size_t).
