Nguyen Anh Quynh 90eb8f2e72 This commit continues the PR #111 
- Allow to register handler separately for invalid memory access
- Add new memory events for hooking:
   - UC_MEM_READ_INVALID, UC_MEM_WRITE_INVALID, UC_MEM_FETCH_INVALID
   - UC_HOOK_MEM_READ_PROT, UC_HOOK_MEM_WRITE_PROT, UC_HOOK_MEM_FETCH_PROT
- Rename UC_ERR_EXEC_PROT to UC_ERR_FETCH_PROT
- Change API uc_hook_add() so event type @type can be combined from hooking types

Sean Heelan dfb4a9d9ad Revert "Remove uc_cb_eventmem_t as it is identical to uc_cb_hookmem_t" 
As pointed out by aquynh the return types are actually different. A
uc_cb_eventmem_t callback returns a bool, while uc_cb_hookmem_t has a
void return type.

This reverts commit cb2b97f26c.
 2015-09-23 12:51:47 +07:00
Sean Heelan cb2b97f26c Remove uc_cb_eventmem_t as it is identical to uc_cb_hookmem_t, as per
