The malloc function allows the programmer to create a block of memory of a given size:

malloc ( long integer lBlockSize ) returns void *

If we decide, during the execution of the program, that we might need to expand, or contract this memory block, we can use the realloc function:

realloc ( void * pBlock, long int lNewBlockSize ) returns void *

When the memory block is no longer used, then it must be returned back to the operating system, by calling the free function:

free ( void * pBlock )
