This line assigns to the tvsend pointer. the tvsend pointer is local to this function. You want to assign to what it points at rather, as the caller pointed it at a struct timeval it can access: *tvsend = *(struct timeval *) icmp->icmp_data; Or struct timeval *tmp tmp = (struct...

Another possibility is to pass the loc_ptr to the function by-pointer instead of by-value. Basically, you'll pass a "pointer-to-pointer" as parameter into the function, the pointer-to-pointer pointing to you loc_ptr. Inside the function, you dereference the arrays memoryaddress from the p...

Four stack pointer registers SP_EL0, SP_EL1, SP_EL2, SP_EL3. Three exception link registers ELR_EL1, ELR_EL2, ELR_EL3. Three saved program status registers SPSR_EL1, SPSR_EL2, SPSR_EL3. One program counter. ABI (9.1节) For the purposes of function calls, the general-purpose ...
Function_return_type(*Function_Pointer_name)(Functionargument list); Here is an example : //It can point to function which takes an int as an argument and return nothing. void(*fpData)(int); //It can point to function which takes a const char * as an argument and return nothing. ...
Like any array would be, the wide string literal is automatically converted to a pointer to its first element (type short int *) where it appears in the function call expression. The corresponding parameter has type unsigned short int *. These types differ in the signedness of ...
This is useful if a programmer wants a function's modifications to a parameter to be visible to the function's caller. This is also useful for returning multiple values from a function.Access and Manipulate Values using PointerThe value of the variable which is pointed by a pointer can be ...
