Your dynamic storage allocator will consist of the following four functions, which are declared in mm.h and defined in mm.c. int mm_init(void); void* mm_malloc(size_t size); void mm_free(void* ptr); void* mm_realloc(void* ptr, size_t size); The mm.c file we have given you...

Small explainations about output of heap command Each line correspond to a malloc chunk, and the heap is dumped after each execution of heap functions (free, malloc, realloc, calloc) addr: is the real address of the malloc chunk usr_addr: is the address returned by malloc functions to us...

This should be applicable to most extensions with exceptions of those with bugs in memory allocations which are caught by Perl's malloc(); which interact with the memory allocator in other ways than via malloc(), realloc(), free(), calloc(), sbrk() and brk(); which rely on special ...
