+.Fa size .
+The space is initialized to all bits zero.
+.Sh RETURN VALUES
+The

+.Sh NAME
+.Nm realloc
+.Nd reallocation of memory function
+.Sh SYNOPSIS
+.Fd #include <stdlib.h>
+.Ft void *
+.Fn realloc "void *ptr" "size_t size"
+.Sh DESCRIPTION
+The
+.Fn realloc
+function changes the size of the object pointed to by
+.Fa ptr
+to the size specified by
+.Fa size .
+The contents of the object are unchanged up to the lesser
+of the new and old sizes.
+If the new size is larger, the value of the newly allocated portion
+of the object is indeterminate.
+If
+.Fa ptr
+is a null pointer, the
+.Fn realloc
+function behaves like the
+.Xr malloc 3
+function for the specified size.
+Otherwise, if
+.Fa ptr
+does not match a pointer earlier returned by the
+.Xr calloc 3 ,
+.Xr malloc 3 ,
+or 
+.Fn realloc
+function, or if the space has been deallocated
+by a call to the
+.Xr free
+or
+.Fn realloc
+function, unpredictable and usually detrimental
+behaviour will occur.
+If the space cannot be allocated, the object 
+pointed to by
+.Fa ptr
+is unchanged.
+If
+.Fa size
+is zero and
+.Fa ptr
+is not a null pointer, the object it points to is freed.
+.Pp
+The
+.Fn realloc
+function returns either a null pointer or a pointer
+to the possibly moved allocated space.
