Function Documentation

radius_exec_program_legacy()

int radius_exec_program_legacy	(	char *	out,
		size_t	outlen,
		request_t *	request,
		char const *	cmd,
		fr_pair_list_t *	input_pairs,
		bool	exec_wait,
		bool	shell_escape,
		fr_time_delta_t	timeout
	)

Execute a program.

Parameters

[out]	out	buffer to append plaintext (non valuepair) output.
[in]	outlen	length of out buffer.
[in]	request	Current request (may be NULL).
[in]	cmd	Command to execute. This is parsed into argv[] parts, then each individual argv part is xlat'ed.
[in]	input_pairs	list of value pairs - these will be available in the environment of the child.
[in]	exec_wait	set to 1 if you want to read from or write to child.
[in]	shell_escape	values before passing them as arguments.
[in]	timeout	amount of time to wait, in seconds.

Returns

• 0 if exec_wait==0.
• exit code if exec_wait!=0.
• -1 on failure.

radius_readfrom_program_legacy()

int radius_readfrom_program_legacy	(	int	fd,
		pid_t	pid,
		fr_time_delta_t	timeout,
		char *	answer,
		int	left
	)

Read from the child process.

Parameters

fd	file descriptor to read from.
pid	pid of child, will be reaped if it dies.
timeout	amount of time to wait, in seconds.
answer	buffer to write into.
left	length of buffer.

Returns

• -1 on failure.
• Length of output.

radius_start_program_legacy()

pid_t radius_start_program_legacy	(	int *	stdin_fd,
		int *	stdout_fd,
		int *	stderr_fd,
		char const *	cmd,
		request_t *	request,
		bool	exec_wait,
		fr_pair_list_t *	input_pairs,
		bool	shell_escape
	)

Start a process.

Parameters

[out]	stdin_fd	pointer to int, receives the stdin file descriptor. Set to NULL and the child will have /dev/null on stdin.
[out]	stdout_fd	pointer to int, receives the stdout file descriptor. Set to NULL and the child will have /dev/null on stdout.
[out]	stderr_fd	pointer to int, receives the stderr file descriptor. Set to NULL and the child will have /dev/null on stderr.
[in]	cmd	Command to execute. This is parsed into argv[] parts, then each individual argv part is xlat'ed.
[in]	request	Current request
[in]	exec_wait	set to true to read from or write to child.
[in]	input_pairs	list of value pairs - these will be put into the environment variables of the child.
[in]	shell_escape	values before passing them as arguments.

Returns

• PID of the child process.
• -1 on failure.
