error code that can be analyzed with the function plerr

Definition at line 156 of file class_gamepad.cpp.

int class_gamepad::GetButtonMapping

(

void

)

[private]

Get the button mapping from the device.

Returns:

error code that can be analyzed with the function plerr

Definition at line 89 of file class_gamepad.cpp.

void class_gamepad::plerr

(

int

ret

)

Print local error function This function prints the error present in the err variable (this is a private variable of the gamepad class). The ret number specifies what kind of error is this, -1 is a error that raises a SIGINT signal, -2 is an warning that allows the program to continue and -3 is a error that prints perror and raises SIGINT.

Parameters:

ret

error code

Returns:

void

Definition at line 188 of file class_gamepad.cpp.

int class_gamepad::RegisterCallback	(	e_type	type,
		int	id,
		void(*)(int value, void *data)	callback,
		void *	data
	)

Register a callback for a specific button or axis.

Parameters:

	type	AXIS or BUTTON (these enums are present in the gamepad class)
	id	number of the button or axis *
	callback	function to be called prototype is void (*callback)(int value,void*data), where the value is the button or axis value and data is the user data
	data	user data to pass to the callback

Returns:

error code that can be analyzed with the function plerr

Definition at line 127 of file class_gamepad.cpp.

int class_gamepad::SetButtonMapping

(

void

)

[private]

Set the button mapping to the device.

Returns:

error code that can be analyzed with the function plerr

Definition at line 108 of file class_gamepad.cpp.

int class_gamepad::StartComm

(

const char *

device

)

Initialize comm with the gamepad.

Parameters:

device

Name of the device to use

Returns:

error code that can be analyzed with the function plerr
