Function Documentation

int wge100Configure	(	IpCamList *	camInfo,
		const char *	ipAddress,
		unsigned	wait_us
	)

Configures the IP address of one specific camera.

Parameters:

camInfo	Structure describing the camera to configure
ipAddress	An ASCII string containing the new IP address to assign (e.g., "192.168.0.5"). If it is NULL or empty, the address in camInfo is used, and the configure packet is not broadcast.
wait_us	The number of microseconds to wait for a reply from the camera

Returns:: Returns -1 with errno set for system call failures. Returns 0 for success Returns ERR_TIMEOUT if no reply is received before the timeout expires

Definition at line 532 of file wge100lib.c.

int wge100ConfigureBoard	(	const IpCamList *	camInfo,
		uint32_t	serial,
		MACAddress *	mac
	)

Sets the permanent serial number and MAC configuration for one camera

Warning:: : This command can only be sent once per camera. The changes are permanent.

Parameters:

camInfo	Describes the camera to connect to
serial	Is the 32-bit unique serial number to assign (the product ID portion is already fixed)
mac	Is the 48-bit unique MAC address to assign to the board

Returns:: Returns 0 for success Returns -1 for system error Returns 1 for protocol error

Definition at line 1194 of file wge100lib.c.

int wge100Discover	(	const char *	ifName,
		IpCamList *	ipCamList,
		const char *	ipAddress,
		unsigned	wait_us
	)

Discovers all WGE100 cameras that are connected to the 'ifName' ethernet interface and adds new ones to the 'ipCamList' list.

Parameters:

ifName	The ethernet interface name to use. Null terminated string (e.g., "eth0"). Empty means to query all interfaces.
ipCamList	The list to which the new cameras should be added
wait_us	The number of microseconds to wait for replies

Returns:: Returns -1 with errno set for system call errors. Otherwise returns number of new cameras found.

Definition at line 372 of file wge100lib.c.

int wge100FindByUrl	(	const char *	url,
		IpCamList *	camera,
		unsigned	wait_us,

	)

Finds a camera matching the given name

Names are of the form:

name://camera_name[@camera_ip][#local_interface]
serial://serial_number[@camera_ip][#local_interface]
any://[@camera_ip][#local_interface]

A name URL indicates the name of the camera to be found. A serial URL indicates the serial number of the camera to be found. An any URL will match any camera, but if more than one camera is found, it will fail.

Optionally, the ip address that the camera should be set to can be specified by prefixing it with a @ sign, and the interface through which to access the camera can be specified by prefixing it with a # sign.

When an ip address is specified, it will be copied into the camera struct.

Parameters:

url	The url of the camera to find
camera	The structure to fill the camera information into
wait_us	The number of microseconds to wait before timing out
errmsg	String containing a descriptive parse error message

Returns:: Returns 0 if a camera was found, -1 and sets errmsg if an error occurred.
