I am having a hard time in manipulating strings while writing module for linux. My problem is that I have a int Array[10] with different values in it. I need to produce a string to be able send to the buffer in my_read procedure. If my array is {0,1,112,20,4,0,0,0,0,0}
then my output should be:
0:(0)
1:-(1)
2:-------------------------------------------------------------------------------------------------------(112)

The manpage says about memset:
#include <string.h>
void *memset(void *s, int c, size_t n)
The memset() function fills the first n bytes of the memory area pointed to by s with the constant byte c.
It is clear that memset can't be used to initialize int array as shown below:
