Function Documentation

◆ process_unix_exec()

process_status_t process_unix_exec ( process_t * process )

Executes the given process as a child process of Tor. This function is responsible for setting up the child process and run it. This includes setting up pipes for interprocess communication, initialize the waitpid callbacks, and finally run fork() followed by execve(). Returns PROCESS_STATUS_RUNNING upon success.

Cleanup standard in pipe.

Cleanup standard out pipe.

Cleanup standard in pipe.

Cleanup standard out pipe.

Cleanup standard error pipe.

◆ process_unix_free_()

void process_unix_free_ ( process_unix_t * unix_process )

Deallocates the given unix_process.

Definition at line 104 of file process_unix.c.

◆ process_unix_get_pid()

process_pid_t process_unix_get_pid ( process_t * process )

Returns the unique process identifier for the given process.

◆ process_unix_new()

process_unix_t* process_unix_new ( void )

Returns a newly allocated process_unix_t.

◆ process_unix_read_stderr()

int process_unix_read_stderr	(	process_t *	process,
		buf_t *	buffer
	)

Read data from the given process's standard error and put it into buffer. Returns the number of bytes read.

◆ process_unix_read_stdout()

int process_unix_read_stdout	(	process_t *	process,
		buf_t *	buffer
	)

Read data from the given process's standard output and put it into buffer. Returns the number of bytes read.

◆ process_unix_terminate()

bool process_unix_terminate ( process_t * process )

Terminate the given process. Returns true on success, otherwise false.

Definition at line 348 of file process_unix.c.

◆ process_unix_write()

int process_unix_write	(	process_t *	process,
		buf_t *	buffer
	)

Write the given buffer as input to the given process's standard input. Returns the number of bytes written.
