Function Documentation

◆ GetDeviceRule()

std::string GetDeviceRule	(	const char *	device,
		const char *	symlink
	)

Get device udev rule.

Parameters

device	Complete device path
symlink	As returned by MakeUdevLink()

Returns: udev rule which makes the device public read/write (0666)

Definition at line 304 of file linux_devices.cpp.

◆ GetDongleRule()

std::string GetDongleRule ( )

Returns: udev rule which makes the dongle public read write (666)

Definition at line 292 of file linux_devices.cpp.

◆ IsDevicePermissionsOk()

bool IsDevicePermissionsOk ( const char * path )

Check device path permissions.

Parameters

path	complete device path

Returns: True if device is exposing read/write permissions.

Definition at line 159 of file linux_devices.cpp.

◆ IsDonglePermissionsWrong()

bool IsDonglePermissionsWrong ( )

Return true if an existing dongle cannot be accessed.

Definition at line 153 of file linux_devices.cpp.

◆ MakeUdevLink()

std::string MakeUdevLink ( )

Get next available udev rule base name.

Returns: first name not used in the sequence opencpn0..opencpn9
