Allocating Storage For Program Data
===================================

   This section covers how ordinary programs manage storage for their
data, including the famous `malloc' function and some fancier facilities
special the GNU C library and GNU Compiler.

Memory Allocation and C

How to get different kinds of allocation in C.

Unconstrained Allocation

The `malloc' facility allows fully general

dynamic allocation.

Allocation Debugging

Finding memory leaks and not freed memory.

Obstacks

Obstacks are less general than malloc

but more efficient and convenient.

Variable Size Automatic

Allocation of variable-sized blocks

of automatic storage that are freed when the calling function returns.
