+<h3>MALLOC(3) Linux Programmer's Manual MALLOC(3)
+</h3>
+
+<h3>NAME
+</h3> calloc, malloc, free, realloc - Allocate and free dynamic
+ memory
+
+<h3>SYNOPSIS
+</h3> #include &lt;stdlib.h&gt;
+
+ void *calloc(size_t nmemb, size_t size);
+ void *malloc(size_t size);
+ void free(void *ptr);
+ void *realloc(void *ptr, size_t size);
+
+<h3>DESCRIPTION
+</h3> calloc() allocates memory for an array of nmemb elements
+ of size bytes each and returns a pointer to the allocated
+ memory. The memory is set to zero.
+
+ malloc() allocates size bytes and returns a pointer to the
+ allocated memory. The memory is not cleared.
+
+ free() frees the memory space pointed to by ptr, which
+ must have been returned by a previous call to malloc(),
+ calloc() or realloc(). If ptr is NULL, no operation is
+ performed.
+
+ realloc() changes the size of the memory block pointed to
+ by ptr to size bytes. The contents will be unchanged to
+ the minimum of the old an new sizes; newly allocated mem-
+ ory will be uninitialized. If ptr is NULL, the call is
+ equivalent to malloc(size); if size is equal to zero, the
+ call is equivalent to free(ptr). Unless ptr is NULL, it
+ must have been returned by an earlier call to malloc(),
+ calloc() or realloc().
+
+<h3>RETURN VALUES
+</h3> For calloc() and malloc(), the value returned is a pointer
+ to the allocated memory, which is suitably aligned for any
+ kind of variable, or NULL if the request fails.
+
+ free() returns no value.
+
+ realloc() returns a pointer to the newly allocated memory,
+ which is suitably aligned for any kind of variable and may
+ be different from ptr, or NULL if the request fails or if
+ size was equal to 0. If realloc() fails the original
+ block is left untouched - it is not freed or moved.
