Hello all,
I am trying to execute the program which is used to
capture an image.
Here I am using the following few lines,
unsigned char * tmp_image_ptr ;
int VIDEO_BUF_SIZE = (320*240*3);
tmp_image_ptr = mmap(0 , VIDEO_BUF_SIZE , PROT_READ |
PROT_WRITE ,MAP_SHARED , Dev , 0) ;
if((unsigned char *)tmp_image_ptr == (unsigned char *)
-1 )
{ printf("MMAP Failed !\n");
sleep(1);
LogErr("MMAP Failed !\n");
continue ;
}
You can refer the following link to see how mmap()
works in c.

But the same program runs perfect on Puppy 2.0 Shocked
Can anybody solve this problem ??? Confused
Thanks & Regards,
Ashwini Patil
