return an array from a function

i want return array function. follow error :
in function 'int getrgb()':
error: invalid conversion 'int*' 'int' in function 'void loop()':

writing : int getrgb()[3] doesn't seem work :
error: 'getrgb' declared function returning array in function 'int getrgb()':

i searched in forum couldn't find syntax it.

code example :

code: [select]


int colorsrgb[3];
int colors_1[3];
int colors_2[3];

int getrgb()
{ colorsrgb[0]=255;
  colorsrgb[1]=0;
  colorsrgb[2]=0;  
  return colorsrgb;
}

colors_1=getrgb();
colors_2=getrgb();





you're getting relatively tricky area, touching on pointers, memory management, etc.  the easiest solution pass array function , write result (rather trying return array).  that is:

code: [select]


int colors1[3];

void getrgb(int colors[3])
{
 colors[0] = 255;
 colors[1] = 0;
 colors[2] = 0;
}

void loop()
{
 getrgb(colors1);
}
