Function Documentation

◆ run() [1/3]

int run	(	const std::string &	what,
		const std::vector< std::string > &	argv
	)

Definition at line 48 of file run.cpp.

◆ run() [2/3]

int run	(	const std::string &	what,
		const std::vector< std::string > &	argv,
		const std::string &	std_input,
		const std::string &	std_output,
		const std::string &	std_error
	)

This runs the executable given by the file name what.

Control returns when execution has finished. Stdin, stdout and stderr may be redirected from/to a given file. Give the empty string to retain the default handle. Any shell-meta characters in the executable, argv and the I/O redirect files are escaped as needed.

Definition at line 252 of file run.cpp.

◆ run() [3/3]

int run	(	const std::string &	what,
		const std::vector< std::string > &	argv,
		const std::string &	std_input,
		std::ostream &	std_output,
		const std::string &	std_error
	)

This runs the executable given by the file name what.

Control returns when execution has finished. Stdin and stderr may be redirected from/to a given file. Give the empty string to retain the default handle. Any output to stdout is stored in the std_output stream buffer. Any shell-meta characters in the executable, argv and the I/O redirect files are escaped as needed.

Definition at line 524 of file run.cpp.

◆ shell_quote()

std::string shell_quote ( const std::string & src )

quote a string for bash and CMD

This performs shell quoting if necessary on input src.

Definition at line 451 of file run.cpp.

◆ stdio_redirection()

static fdt stdio_redirection	(	int	fd,
		const std::string &	file
	)

static

open given file to replace either stdin, stderr, stdout
