Macros
#define	SYNPROTO_TIMEOUT_MS 5000
	Timeout to wait between keepalives before disconnecting.

#define	swap_32(num) ((((num)>>24)&0xff) \| (((num)<<8)&0xff0000) \| (((num)>>8)&0xff00) \| (((num)<<24)&0xff000000))
	Swap byte order in a 32-bit integer from network to native.

#define	swap_16(num) (((num)>>8) \| ((num)<<8))
	Swap byte order in a 16-bit integer from network to native.

#define	synproto_exval_32(buffer, offset) (swap_32( ((uint32_t)&(buffer[offset])) ))
	Perform endianness swap on a 32-bit integer from a buffer if needed.

#define	synproto_exval_16(buffer, offset) (swap_16( ((uint16_t)&(buffer[offset])) ))
	Perform endianness swap on a 16-bit integer from a buffer if needed.

Functions
void	synproto_dump (const char *buf, size_t buf_sz)
	Given a buffer with a string from the Synergy server, dump it into a more human-readable form.

size_t	synproto_vprintf (char buf, size_t buf_sz, const char fmt, va_list vargs)
	Given a format string and tokens, write those tokens into a buffer using specific tokens listed here.

uint32_t	synproto_send (int sockfd, uint8_t force_sz, const char *fmt,...)
	Send a formatted string to the Synergy server with tokens as specified for synproto_vprintf().

int	synproto_parse_and_reply (struct NETIO_CFG config, const char pkt_buf, uint32_t pkt_buf_sz)
	Given a buffer with a string from the Synergy server, parse it and respond or simulate OS activity as directed.

Detailed Description

Tools for dealing with the Synergy protocol.

Macro Definition Documentation

#define synproto_exval_16	(		buffer,
			offset ) (swap_16( ((uint16_t)&(buffer[offset])) ))

Perform endianness swap on a 16-bit integer from a buffer if needed.

Parameters

buffer	Buffer to pull integer out of.
offset	Offset of the buffer (in bytes) of the integer to pull.

#define synproto_exval_32	(		buffer,
			offset ) (swap_32( ((uint32_t)&(buffer[offset])) ))

Perform endianness swap on a 32-bit integer from a buffer if needed.

Parameters

buffer	Buffer to pull integer out of.
offset	Offset of the buffer (in bytes) of the integer to pull.

Given a buffer with a string from the Synergy server, parse it and respond or simulate OS activity as directed.

Parameters

pkt_buf	The buffer in which the server transmission is stored.
pkt_buf_sz	The size of pkt_buf.

Send a formatted string to the Synergy server with tokens as specified for synproto_vprintf().

Parameters

sockfd	The socket identifier/handle on which the Synergy server is connected.
force_sz	Force the preliminary size of the response packet to this number. If 0, the number is calculated automatically.
fmt	Format string using the tokens from synproto_vprintf().

Given a format string and tokens, write those tokens into a buffer using specific tokens listed here.

Parameters

buf	Buffer to write the formatted response to.
buf_sz	Size of buf in bytes.
fmt	Format string using the tokens below.
vargs	A va_list of tokens already initialized with va_start().

Token	Specifies
%ni	Where n is a single-digit number, an integer n-bytes wide.
%s	A null-terminated string.
