Free Invalid Pointer In C at John Dunbar blog

Free Invalid Pointer In C. Just because something is an address doesn't. Attempting to free an invalid pointer (a pointer to a memory block that wasn't allocated by calloc, malloc, or realloc) may affect subsequent. If your code trashes a pointer used by some other code, other code may wind up calling free on an invalid pointer. So, there's no need to check the pointer before calling free. You're attempting to free something that isn't a pointer to a freeable memory address. It is also creating a memory leak because the address of the malloc'd memory is being replaced. “free () invalid pointer” is an error message indicating that a program is attempting to deallocate memory that has already been deallocated or was never allocated in the first. Even though the term invalid pointer is not defined in the c/c++ terminology, there are a few cases in which the programmer breaks these. When the free () call is executed, it's trying to free an invalid address. The function frees the memory buffer that was previously allocated using the malloc, calloc, realloc, and aligned_alloc functions. If ptr is a null pointer, the function does nothing. The free function is declared in the header file as follows: Remove the & from the fread () and fwrite.
