i have a tructure in c that i need to transform into jna:

*

typedef * *enum*

{

IDLE,

PREALARM,

ALARM,

ALERT,

TAPE

} State;

*

typedef * *struct*

{

*int* size;

*bool* valid;

*bool* active;

*bool* signal;

State state;

*int* last_write_index;

*int* last_read_index;

time_t last_image_time;

*int* last_event;

*int* action;

*int* brightness;

*int* hue;

*int* colour;

*int* contrast;

*int* alarm_x;

*int* alarm_y;

*char* control_state[256];

} SharedData;

i tried to transform it and made:

import com.sun.jna.Pointer;

public class SharedData extends Structure { public int size; public boolean valid; public boolean active; public boolean signal; //public state; public int last_write_index; public int last_read_index; public long last_image_time; public int last_event; public int action; public int brightness; public int hue; public int colour; public int contrast; public int alarm_x; public int alarm_y; public byte[] control_state= new byte[256]; @Override protected void useMemory(Pointer m) { super.useMemory(m); super.read(); } @Override protected void useMemory(Pointer m, int offset) { super.useMemory(m, offset); }

}

i didnt find a way to transform enum into jna. to what transforms enum?
