This code has several style issues:
1. Always put blank line after declarations
2. Use unsigned where ever it makes sense as a matter of habit.
unsigned int i, count = 0;
3. Don't add casts where not necessary, it reduces compiler type checking
and is a bad habit. In this case evs[i].data.ptr is void *
and therefore no cast is needed.
