Here is the caller graph for this function:

int fiu_rc_string	(	const char *	cmd,
		char **const	error
	)

Applies a remote control command given via a string.

The format of the string is not stable and is still subject to change. At the moment, this function is exported for consumption by the libfiu utilities.

Parameters:

cmd,:	A zero-terminated string with the command to apply.
error,:	In case of an error, it will point to a human-readable error message.

Returns:: 0 if success, < 0 otherwise.

int fiu_rc_fifo ( const char * basename )

Enables remote control over a named pipe.

The name pipe path will begin with the given basename. "-$PID" will be appended to it to form the final path. After the process dies, the pipe will be removed. If the process forks, a new pipe will be created.

Once this function has been called, the fiu-ctrl utility can be used to control the points of failure externally.

Parameters:

basename Base path to use in the creation of the named pipes.
