16.9. Dynamic Memory Management
Many programs, including those that work with dynamic data structures for example, depend on the ability to allocate and release blocks of memory at runtime. C programs can do that by means of the four dynamic memory management
functions declared in the header stdlib.h, which are listed in Table 16-22. The use of these functions is described in detail in Chapter 12.
Table 16-22. Dynamic memory management functions
