Hi,
I have a little question.
I have this code.

int *MyFunc()
{
int *ret;

ret = (int*) malloc(a*sizeof(int)); /*here was allocated some bytes*/

/* do something with ret*/

return ret;
}

main()
{
int *r;

r = MyFunc();

printf("My r have %d bytes", ????? );
for(i=0; i< ????; i++)
if( r[i] == 20 )
/*do something*/

}

How can i discover what is the size of my pointer 'r'? How much can my 'i' be increased?


thank's
