Function Documentation

◆ buf_flush_to_pipe()

int buf_flush_to_pipe	(	buf_t *	buf,
		int	fd,
		size_t	sz
	)

Write data from buf to the pipe fd. Write at most sz bytes, decrement *buf_flushlen by the number of bytes actually written, and remove the written bytes from the buffer. Return the number of bytes written on success, -1 on failure. Return 0 if write() would block.

◆ buf_flush_to_socket()

int buf_flush_to_socket	(	buf_t *	buf,
		tor_socket_t	s,
		size_t	sz
	)

Write data from buf to the socket s. Write at most sz bytes, decrement *buf_flushlen by the number of bytes actually written, and remove the written bytes from the buffer. Return the number of bytes written on success, -1 on failure. Return 0 if write() would block.

◆ buf_read_from_pipe()

int buf_read_from_pipe	(	buf_t *	buf,
		int	fd,
		size_t	at_most,
		int *	reached_eof,
		int *	socket_error
	)

Read from pipe fd, writing onto end of buf. Read at most at_most bytes, growing the buffer as necessary. If read() returns 0 (because of EOF), set *reached_eof to 1 and return 0. Return -1 on error; else return the number of bytes read.

◆ buf_read_from_socket()

int buf_read_from_socket	(	buf_t *	buf,
		tor_socket_t	s,
		size_t	at_most,
		int *	reached_eof,
		int *	socket_error
	)

Read from socket s, writing onto end of buf. Read at most at_most bytes, growing the buffer as necessary. If recv() returns 0 (because of EOF), set *reached_eof to 1 and return 0. Return -1 on error; else return the number of bytes read.
