C Programming Free Null Pointer at Declan Rubio blog

C Programming Free Null Pointer. The free () function in c is used to free or deallocate the dynamically allocated memory and helps in reducing memory wastage. This c tutorial explains null pointer in c with examples. The null constant is defined in the header files stdio.h , stddef.h as. A null pointer in c is a pointer that doesn't point to any of the memory locations. If (p_some_variable == null) {. A pointer value can be null, which means it does not point to any object. The cleanest way to get a null pointer is by writing null, a standard macro. I'm writing a c function that frees a pointer if it was malloc()ed. The c free () function cannot be used to free the statically. If you had set the pointer to null after free, any attempt to read/write through that pointer later would result in a segfault, which is generally preferable. It is a type of pointer that doesn’t point to any memory location, but the zeroth memory. #include <stdio.h> int main(void) { int * p_some_variable = null; You can check if a pointer is a null pointer by comparing it to null: The pointer can either be null (in the case that an error occured and the.
