Hello I can't truly understand why the free process returns in an error. I got this code in C: int LuffarschackStart(void) { /* to avoid the program from closing */ char readEnd; int i = 0; board_type *board = malloc(sizeof(square_type)); if (board == NULL) { printf("Could not allocate the memory needed..."); scanf("%c", &...
Hi, I have a question regarding free() in C. Suppose I have a pointer to some struct (say node *ptr).. after freeing it can i Initialize it to NULL and make it point to some new location using malloc() or realloc()? For Example: node *ptr=NULL; ptr=realloc(ptr,sizeof(node)); //works exactly like malloc /* Do some operations on ptr */...

Helo, I am using chipmunk as a physics engine in my game. The problem is I now want to free all the children and then the space itself, so I can create a new space for the new level. I tried this: cpSpaceFreeChildren(space); cpSpaceFree(space); But it does not work and fails in: cpHashSetReject(cpHashSet *set, cpHashSetRejectFunc ...
I am looking for a good (stable enough, intuitive enough, and the more technologically modern and advanced - the better) free PHP-based online groupware/collaboration system. 100% UTF-8 is a requirement. OOP-style code is an advantage. And collaborative mindmapping would be a cool feature to have. The team is of ~20 people. Any suggestio...
Is there a one-liner that will free the memory that is being taken by all pointers you created using mallocs? Or can this only be done manually by freeing every pointer separately? ...
I'm trying to free up the memory I've allocated with malloc, but the free command doesn't seem to do its job properly according to Eclipse's debugger. How's this possible? Below is a screenshot of my debugger after it supposedly freed up seCurrent->student->year, which is clearly not the case. year was allocated using malloc. ...
I get a segmentation fault after freeing a certain pointer: free(studentDB->name); I can get its value without any errors or warnings: printf("[DBG] studentDB->name: %s\n", studentDB->name); However, as I said, the program crashes when I try to free it. What are the most common causes for a free command leading to a segmentation fa...
This question was asked to me in an interview. Suppose char *p=malloc(n) assigns more than n,say N bytes of memory are allocated and free(p) is used to free the memory allocated to p. can heap manager perform such faulty allocation ? what happens now, will n bytes are freed or N bytes are freed? is there any method to find how much m...

Hi, I'm having trouble with what should be a simple program. I've written a single linked list implementation in C using void* pointers. However, I have a problem, as there is a possible memory leak somewhere, however I checked the code using valgrind and it detected no such errors. But when all the memory is free'd there is still som...
