Function Documentation

char* net_Gets	(	vlc_object_t *	p_this,
		int	fd,
		const v_socket_t *	p_vs
	)

Reads a line from a file descriptor.

This function is not thread-safe; the same file descriptor I/O cannot be read by another thread at the same time (although it can be written to).

Returns:

nul-terminated heap-allocated string, or NULL on I/O error.

		int	fd,
		const v_socket_t *	p_vs,
		const void *restrict	p_data,
		size_t	i_data
	)

Writes data to a file descriptor.

This blocks until all data is written or an error occurs.

This function is a cancellation point if p_vs is NULL. This function is not cancellation-safe if p_vs is not NULL.

Returns:

the total number of bytes written, or -1 if an error occurs before any data is written.

int rootwrap_bind	(	int	family,
		int	socktype,
		int	protocol,
