Classes

ISystem

class ISystem {
public:
    static void GetArchitecture(char * buffer, size_t len);
    static architecture_t GetArchitecture();
    static void Sync();
    static const char * Label();
    static const char * ReleaseState();
    static bool SetBindServiceCapability(const char * path);
    static bool IsVirtualMachine();
};

Public functions

GetArchitecture (static function)
The function is used to get a string containing the architecture of the machine (e.g. armv7l on IP811)

Parameters

char * bufferTo hold the architecture string
size_t * len The length of the buffer
GetArchitecture (static function)
The function is used to get the architecture of the system.

Return value

Returns the architecture of the system (ARM or X86_64) as an enum of type architecture_t.
Sync (static function)
A call to this function will synchronize data on disk with memory. Any buffered data in memory is writen out to disk.
Label (static function)
The function is used to get the label of the installed application platform.

Return value

Returns the actaul label of the App platform.
ReleaseState (static function)
The function is used to get the release state of the installed application platform.

Return value

Returns the actaul release state of the App platform.
SetBindServiceCapability (static function)
The function is used to set the capability flag CAP_NET_BIND_SERVICE for the pathname pointed to by path. The flags assocaited with the capability are CAP_EFFECTIVE and CAP_PERMITTED. This function is strictly used by the Manager App.

Return value

If the capability is successfully set true is returned; otherwise false.
IsVirtualMachine (static function)
Checks if the system is running on a virtual machine.

Return value

In case of virtual machine achitecture true is returned; otherwise false.

Data types

architecture_t

typedef enum {
    ARM,
    X86_64
} architecture_t;

Overview

The enum architecture_t defines the two achitectures supported by the interface.

Values

ARM
X86_64
