Now since unlike free, munmap also takes length as parameter, therefore I put length as an additional information in the mapped memory. The code for my malloc and free is shown below. The starting address for the new mapping is specified in addr. They can contain many different elements such as images, icons, equations, text, symbols, and more. In addition: The behaviour of brk () and sbrk () is unspecified if an application also uses any other memory functions (such as malloc (), mmap (), free () ).
