ISystem

class ISystem {
public:
    static void GetArchitecture(char * buffer, size_t len);
    static architecture_t GetArchitecture();
    static const char * GetArchitectureName();
    static void Sync();
    static const char * Label();

Public functions

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

Parameters

char * buffer	To hold the architecture string
size_t * len	The length of the buffer

The function is used to get the architecture of the system.

Return value

Returns the architecture of the system as an enum of type architecture_t.

The function is used to get the architecture name of the system.

Return value

Returns the architecture name of the system as a const char *.

A call to this function will synchronize data on disk with memory. Any buffered data in memory is writen out to disk.

The function is used to get the label of the installed application platform.

Return value

Returns the actual label of the App platform.

The function is used to get the label of the underlying rootfs of the installed application platform.

Return value

Returns the actual rootfs label of the App platform.

The function is used to get the release state of the installed application platform.

Return value

Returns the actual release state of the App platform.

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.

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,
    ARM64
} architecture_t;
